Compensation of PWM Inverter Voltage Errors based on Measurement of DC-Link and Output Voltages

摘要

In theory, a PWM inverter generates output voltages that are proportional to the input duty-cycles. Asrnthis is not the case in reality, this paper proposes an approach to measure the real output voltages and,rnhence, to compensate for the non-linear behavior. The method is proved by measurements.
