More Topologies. PowerEsim's Sponsors More Electric energy is transformed to be the engine of any power supply. This kind of electronic system converts electric energy to mechanical energy from the source to a given load. In this case the device is more accurate to be referred as a "power converter" than a power supply. These sections are automatically designed for you as you control the desired specifications.

Then the fast analysis tools allow you to simulate the circuit and get the same data that you would get on the test-bench. Why use Power-Witts in the circuit design stage?

Power-Witts was designed by a world-class power supply designer who asked the question "what technical details do I have to solve over and over again that could be better solved in software? Furthermore, the designer asked "What kind of data do I want the simulation to give me to aid me in testing and troubleshooting breadboards, brassboards, and prototypes?

And it can do it much faster than spice models. And stability analysis is easy because it calculates voltage loop or current loop Bode plots and other frequency domain plots In addition, as you go through the design process you have choices of what types of circuits to use for filtering, feedback control, switching, etc. This speeds up the process of design immensely because you can first pick a design for economy, then cut and paste different selections into the design as higher performance is needed.

The simulation tools allow you to quickly evaluate a design and determine whether it is over or under designed. What is the return on investment?

Design costs are the most expensive costs a business faces not only because of direct costs but also lost opportunity costs because the design is not yet on the market. This inexpensive software not only takes many days off the design time, but allows design variations to be tried quickly and accurately.
