Power Electronics Design Methods

I first saw this practically in the Orthodox Cherokee SMPS. This is where we differentiate from Engineered Products and just Mass Production without following standards. The Cherokee SMPS was a work of art, perfect in all respects.

The Copper Desert or Isolation Land

There is a No Man’s Land in PCB. Any good power electronics designer should/will know. Product Safety and HV Isolation, Quality and Reliability all depend on this.

High Energy Circuits

Power Electronics Design Methods

These things don’t come overnight, it is a culture, learning, experience and integrity of some of these American Firms. Reliability and Product safety are important. Every human values his life very much. A manufacturer too should appreciate this.

Coming back to isolation, Keep in mind creepage distance, High energy circuits and Low voltage circuits should have clear isolation, use the best insulation. Fire and shock hazard. Mains HV transitions, spikes.

Regulated High Voltage Power Supply

Power supply faces all these, even other areas where a Human Life or Property can be endangered.

HV High Voltage Reliability and Safety

Use a Servo Stabilizer or CVT Constant Voltage Transformer or at least an Isolation Transformer. The First Defense form HV Surges, Spikes.

High Voltage Polyester & Polypropylene Metallized Capacitors in Stepdown Supplies should be Fire Retardant & Self Healing with a MOV too.

Tech Ideas as Feedback – Computers

These are some ideas, comments, feedback and communication that i have had over the past many years online. 2006-11

Photonic Speeds

The real speed can be seen when we switch completely to photons and photonic circuits. No more electrons. Blazing Tera Hertz Transfer Speeds. Just a few decades away. Another smart alec comment i made at the site of a major speed provider.

System-on-Chip – SoC – IP

3D Hologram Newspaper

3D Hologram Newspaper

An Interactive 3D Hologram Newspaper that is Projected by a Small Rechargeable Pendent or Desktop Device. It can be a MultiMedia 3D Book, Magazine or Newspaper. It can be used even when lying down on a bed. It can be used on a Restaurant, the group can read the day’s Paper. (An idea i gave at a website with a Questionnaire, years ago)

Digital Signal Processing – DSP

Rechargable Wireless Peripherals

Buy only those Wireless Peripherals or Even Keyboard / Mouse, that can be recharged & dockable or on a Ferrite / Magnetic, No wire/metal charging base. (Just drumming up an old idea of mine)

Storage Tripod Hybrid for Reliability Speed

The wear and tear, fragmentation on HDD can be reduced using a Tripod Hybrid. Access Speed improves too…

Top Layer is RAM Drive with Li-ion Battery. Second layer is Flash. Third is the Spinner HDD.

All active files of user are on RAM drive and backed up on Flash by intelligent Drive (not CPU). The files go into HDD after they have been stable for over an hour. As HDD sizes are increasing. The files and file system can be like svn and maintain 3 versions of all dynamic files. This is useful for user also and HDD too.

Storage Tripod Hybrid for Reliability Speed

Static files like Binaries can be on one area of HDD. Frequently accessed binaries are promoted to flash layer. Extremely frequent to Ram Layer. The HDD now is less stressed and lasts longer and is a stable backup. Power failures immune.

Bare Essentials

A supercap built into a HDD. On Brownout OR Power Fail. The falling ramp is detected beyond an isolating diode. It says to HDD uC … Look there is something funny with power now. The HDD uC at once finishes the work at hand, drawing its juice from the stable supercap, parks its heads and goes to sleep.

When power is stable again, it wakes up and the supercap is replenished too. This way damage to HDD is avoided, these happen when .. battery connection problems in laptop or mains power fluctuations or switching power systems carelessly. It makes HDD idiot proof at least electrically.

The SmartRadio – eNewspaper Delivery

A Jpeg browser device like Digital Photo Album. It has a LCD Screen and a FM Radio interface. It costs less that $100 or comes free with 5 yrs subscription to a paper. – The SmartRadio

In the early morning it downloads the media on a built-in locked FM receive only radio.The FM newspaper station just transmits a few minutes of encrypted digital data. This is stored and static jpeg pages generated, which can be easily viewed and read using scroll and zoom using a convenient handheld device.

XML-HTML FM Radio – FM Radio enhancements

FM radios consume less power and are affordable, now we should add a small LCD display like you have in cellphones. Xml should be frequency modulated and transmitted by fm stations in adjoining bands.

Electronic Engineering Magazines

Xml is demodulated by fm radio and displayed in the lcd display on radio. This way news can be transmitted to many people without internet or tcp/ip. This is just one way broadcast of xml or html information, it need very less freq. Even html, jpeg, png and flash can be broadcast by fm radio. Product advertisements can also be sent in this format. Just tune into your xml fm radio station with your color lcd portable radio and presto news, ads, pictures, semi static but can reach millions. The radio tuner can tab over different stations.

Cost Effective eNewspaper Delivery Jpeg Radio

If it works and people start using it, it could be a standardized paper reader which can manage multiple subscriptions. The subscription can be bought in the form of a chip card or monthly billing. Then it can move to color and slowly to WiMax with Rich Media and Accessibility like Read aloud Text, Translate and Search. This depends on how far the media can go in modernizing and how safe the system is. Too bad that looks like a Tablet Computer again.

Everything is converging to Wireless Internet and Cloud Computing. The Tech Prophets had foreseen this phenomena prematurely.Then there was a oracle from the sky …..

There is enough bandwidth on the sides to accommodate a Low Resolution Jpeg or GIF Animation. Seeing this on a Color LCD Radio will make it Smart.

Now we have SMS Song Requests. The names of the Enthusiasts can come on the LCD screen by xml. Some Text can be easily pumped on FM Frequencies as a thin xml file. Even the details of the Radio Show.

SmartRadio may be One way communication. But we can add static pictures and text !

We could also make a Hybrid Device that combines the Mobile Data or Wi-Fi.

Speech to Text and Text to Speech Devices

This was an idea for Apps like Browser and Email..This is for any device phone or laptop a user interface for people who need it like when Cooking or Driving. People with disabilities or injuries. BlackBerry Phone had a nice incorporation of the text to action.

Added in 2015

We have three things Text-2-Speech, Speech-2-Text and Speech-2-Action. This makes any Gizmo or Computer Interface with a Human without the use of Limbs.

2009 Note Below –

Spoken Words or 14 Seconds of Voice Message. Alternative to Thumbing. A Text to Speech Engine Server Side. With Adaptive Mimicry Voice Synthesizer for that User ID. .

A MultiMedia Service without too much local or server load. Short Compressed Audio Files Recorded and Rendered by Flash Inline Inserts on the Web Application.

Speech talking calculator by Telesensory Systems

A Vintage Speech Equipment The Speech+ talking calculator by Telesensory Systems, Inc.

First idea enables people who just cannot type their message, and need to speak a few words, which is recorded by microphone and sent like a Compressed Voice mail.

Second Idea depends on first idea to train a server side engine, a Text to Speech tuned by earlier voice messages.

When a person cannot read the text, like when driving or in a private gathering, he can press read all incoming messages. Then the server will process text to speech matched according to the User ID Speech Profile and Read out loud in his Headphones.

Bot as SMD Soldering Aid

I need a Bot to help me with soldering. Years of looking at Monitors and Double Clicking Mouse, have taken their toll .

Please develop a Camera/Monitor assisted Soldering/Desoldering Workstation. The Miniature Soldering iron manipulated by a Joystick into position and then press the fire button, a tiny blob of solder paste lands on the Junction on Focus. Now press the fire again, a Perfect Shiny Soldered Joint.

2016  – There is a solution from Martin that is close to what i had in mind.

The Expert 10.6 rework stations facilitates the reliable and precise rework of BGA-, CSP-, and QFN-components, connectors and sockets. Innovative technologies.

The Expert 10.6 rework stations

What we need is a Desktop Aid for SMD prototype fabrication and SMD Card Repairs. Not for manufacturing. To be used by Design Centers and Service Centers.

The card to be populated or repaired can be moved in X-Y-Z axis using  a PC. The Soldering Tool and the adhesive and paste dispensing tool should sync with the PCB Position. Then Soldering and Desoldering should be automated by the machine with camera, after Package type is keyed in. It is a Hands Free Soldering machine with the PC Monitor and HD Camera helping the visualization of the Job

USB or Ethernet Processing Boost

A software and External Hardware, Interfacing on LAN or USB or even WiGig when it comes. The hardware contains HDD/Flash, RAM and RAW Processing power. This is not like Hyper Threading or multi-core cpu, but addresses same issue.

USB or Ethernet Processing Boost

The Software sees resources load on PC and when it feels RAM, CPU or HDD is getting stressed; it moves some work to the external box which is on standby consuming low power. Like playing music is lesser priority then say checking email. The Software Resource manager moves the Music Player and dependencies open in RAM to the Resource outside via USB and makes a Glitch-less switch. This can be remembered as a setting and used whenever the external resource is plugged in. Like RAID but for Home/Small Office users to use redundant capacities. Hardware scales up/down with needs and does not hog electrical power.

A lot of Processing Power and other resources go waste, consuming valuable energy in the present desktops. How faster things can be if all peripherals were on TCP/IP and Wireless (optical). This way an external resource box can directly play the speakers or print too without taking Main CPU time.
