Abstract

The power semiconductors of one bridge leg of the buck-type input stage of a three phase buck+boost PWM rectifier are integrated into a novel power module. The basic function of the rectifier system is described, and the current stresses on the power semiconductors are calculated analytically. By an experimental analysis of the module, the switching losses of the power transistors are determined, and the system efficiency and the loss contributions of the different components are calculated. This gives a basis for the selection of advantageous operating parameters of the module in an industrial application
