Abstract

This paper presents a digital implementation of a new and simple control technique of a hybrid filter to compensate harmonics of a nonlinear load. The hybrid filter consists of a shunt passive filter (PF) along with a series active filter (AF). A diode bridge rectifier with R-L load is considered as a nonlinear load. An indirect current controlled voltage source inverter (ICC-VSI) is considered as an AF. A simple control algorithm based on proportional plus integral control of a self-supporting DC bus voltage of the series AF is implemented on a TMS320C31 DSP. A laboratory prototype model of the proposed hybrid filter is developed and its performance is examined. Experimental results are given and discussed in detail
