11.1 Overview
11.1.1 Introduction
Currently, an increasing part of generated electric energy is converted through AC–DC converters,
before it is consumed in the nal load. e majority of systems apply a diode rectier (Figure 11.1).
Diode rectiers are simple, reliable, robust, and cheap. However, diodes rectiers enable only unidirec-
tional power ow and cause a high level of harmonic input currents; moreover the performance varies
signicantly with load [1]. Performance can be improved by the application of input inductance but it
demands installation of a bulky three-phase choke (Figure 11.2).
During the last years, PWM converters have ...
