Abstract :
This paper investigates a three-phase shunt power filter based on three standard three-phase interconnected converters. Compared with the usual three-phase shunt filter, the proposed converter permits to reduce the dc-link voltages and reduce either harmonic distortion or switching frequency. Control strategies suitable to control the filter and circulating currents as well as the three dc-link voltages are presented. A PWM strategy is designed to command the converter according to the reference voltage generated by the controllers. Simulation and experimental results are presented.
