Transient Characteristics of Power Switches

Power switches are building blocks of power electronics, with their characteristics fully exhibited only in power electronic converters. At the system perspective, power switches are one of main factors in power electronic systems and determine electromagnetic transients when coupled with other factors like the main-power circuit and control algorithms. As the critical bridge between the software and hardware, they are the places where information and energy mix together, displaying significant nonlinear behaviors. Therefore transient characteristics of power switches are the key to investigate power electronic transients, as determined by the internal physical mechanism and external influential factors.
