PowerEsim – Online power supply design

PowerESIM is a eCAD tool for switching power supplies on the Internet. Web Based Switching Power Supply design and Simulation.

PowerEsim – Online power supply design

The most important characteristic powerEsim is that it provide a virtual laboratory environment for engineer to verify and fine tune their design. Experience engineer use it to optimize their design by saving a lot of time than in real bench.

PowerEsim - Online power supply design

The circuit simulator is a combination of iteration, equation based apporoach and time step integration. The circuit is defined by non-linear equations and the simulator will first solving the switching condition solution for t=infinity by bracketed iteration, then fine step of point by point results will be generated by those equations for V, I and loss analysis.

“In a real laboratory, engineers have the ability to feel the heat, measure the stress, wind real transformers and wait and see how long until the unit gets burned. With our seamless integration of a variety of tools such as thermal, MTBF, Life, DVT, Waveform, etc., users can now do the same things in PowerEsim virtual environment.”

ADS7816 – 12-Bit High Speed Sampling AD

The ADS7816 is a 12-bit, 200kHz sampling analog to- digital converter. It features low power operation with automatic power down, a synchronous serial interface, and a differential input. The reference voltage can be varied from 100mV to 5V, with a corresponding resolution from 24mV to 1.22mV. – From TI Applications

ADS7816  – 12-Bit High Speed A/D Converter

Low power, automatic power down, and small size make the ADS7816 ideal for battery operated systems or for systems where a large number of signals must be acquired simultaneously. It is also ideal for remote and/or isolated data acquisition.

ADS7816 - 12-Bit High Speed Sampling AD

12-Bit High Speed Micro Power Sampling Analog-to-Digital converter

The ADS7816 is a classic successive approximation register (SAR) analog-to-digital (A/D) converter. The architecture is based on capacitive redistribution which inherently includes a sample/hold function.

The converter is fabricated on a 0.6µ CMOS process. The architecture and process allow the ADS7816 to acquire and convert an analog signal at up to 200,000 conversions per second while consuming very little power

MOSIS – Affordable Integrated Circuits Fabrication

MOSIS Is An Multi-Project Wafer (MPW) Integrated Circuit (IC) Fabrication Service Provider.

MOSIS – Affordable Integrated Circuits Fabrication

“MOSIS is operated by the Information Sciences Institute at the University of Southern California (USC). MOSIS merges multiple IC designs submitted by both companies and universities onto multi-project wafers (MPW) to share the cost of fabrication among multiple users.”

HyperPhysics – Educational Resource Physics Electronics

HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or “cards”, true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network..

Electronics Concepts at HyperPhysics

Students should go thru this website from cover-to-cover, It is a work of knowledge that is priceless

Ampere Law at HyperPhysics

Ampere’s Law at HyperPhysics

“Ampere’s Law states that for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop.”

Materials and Inventory Management

The Inventory of a Firm should be Open within an Organization. Searching with a browser, Integrateable with departmental webware/intranet. With a very easy readable non-programmer friendly API.

Components Parts Kits and Materials

The Search must be based on Multiple Keywords, Filters or Tags. Dormant Inventory and Parts/Equipment/Furniture not on any live project anymore, Excess Inventory and Obsoleted Parts due to Tech Advancement; should be flagged. This enables other departments to use it, consume it for Maintenance or Research projects or integrate into new designs if not-obsolete.

electronic components

If found to be valueless, damaged or worn-out by all departments and responsible engineers, then inventory should be sold or given away. The Employees can be the first customers for an inhouse Corporate Garage Sale. An un-organized, complexly-computerized and non-transparent/blocked Stores will end up in a Flea Market.
