Abstract

This paper analyzes the losses of the switching device for a full bridge inverter connected to the grid. As the development of power conversion system, losses are dominant factors in judging the efficiency of a system. The losses of a switching device can be divided into switching loss and conduction loss, both of which can be estimated by analyzing periodic switching waveform. The switching loss is generated when the switch is turned on and off, while the conduction loss is generated when the switch is turned on. The estimated losses of the MOSFET switch are compared with the simulation results.
