Simulation Study of Seven-Level Shunt Active Filter

Abstract

In high power electrical equipment, especially the ship propulsion system, in this kind of adjustable speed motor drive, to solve the circuit components in the system or front-end rectifier harmonic and power quality problems, through the thinking of multilevel inverter, seven levels of shunt active power filter simulation results can be got after acquisition of harmonic current obtained by simulation and PWM control. In addition, the compensation current and load current waveform are got, and show the topology of the active filter module.
