Abstract

The purpose of this paper is to determine the efficiency of a specific active power line conditioner (APLC) system. The APLC is a type of active filter, which cancels line current harmonics caused by nonlinear loads, by injecting a compensation current. However, because of the presence of semiconductor switching devices in the APLC, the switching and conduction losses need to be considered. Computer simulations for two load current test cases illustrate the trade-off between circuit efficiency and performance as switching frequency increases.
