Abstract

This paper presents a loss analysis and compares three pulse width modulation (PWM) methods applied in a three-phase grid-connected bidirectional inverter for an energy storage system. The losses in switching devices and output low pass filters are theoretically analyzed by using PWM control techniques. Grid-connected bidirectional inverters are designed by using PWM techniques, and the designed inverters are simulated to verify the analysis results.
