Voltage Waveform Control of Three-Phase PWM Inverter Based on the Output Harmonic Current Feed-Forward Compensation


Article Preview

A control scheme based on the load harmonic current feed-forward compensation for three-phase pulse width modulated (PWM) voltage source inverter is presented. This control scheme is designed to improve the quality of the three-phase inverter output voltage under nonlinear load. The model of the control system in the d-q coordinate system is established based on the traditional double loop control where the feed-forward current is taken from a band pass filter. In order to analyze this compensation method, the system is divided in to two subsystems and each subsystem is analyzed, and the structure of the output harmonic current feed-forward compensation channel is given. Simulation and experimental result validate that the proposed feed-forward compensation method has a good steady state performance and dynamic responses.
