POWER ELECTRONICS

In a circuit‐oriented simulation environment, there are three levels of modeling: component level, circuit level and system level. A system‐level simulation can merge the interaction of different modules in a system, for example, a converter, a controller, source, and load. A very appropriate level of circuit‐level modeling must be chosen to incorporate the functionality and large signal behavior of switching converters, fast inner control loops, and fundamental power electronic switch operation. The PSIM circuit simulator approaches the idealized switching of semiconductors instead of detailed physical models with a good degree of analog and digital circuits required for designing circuits. A simple circuit that can be studied in a circuit simulator is a half‐wave rectifier, because it can be used for cross‐examination of exact mathematical calculations with their simulations in a circuit simulator as well as their numerical computation using a platform such as MATLAB.
