Abstract

The use of power electronic converters to control the power flow from the AC grid to a DC load leads to reactive power increase and affects the efficiency. These two important energy quantities depend on the structure of the converter topology, the operating switching frequency and the power percentage related to the nominal power. In this paper, the quantitative changes of the power factor and the efficiency each as a function of the output active power and for different switching frequencies are investigated, taking into consideration four basic converter topologies
