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