Beschreibung
Zusammenfassung:	A pulse width modulator (PWM) (102) of a multi-phase power converter (100) is provided. The PWM includes a signal modulator (302) that corresponds to each phase of the converter. Each signal modulator of the PWM is configured to receive a unique triangle carrier signal, receive a unique sine wave signal, compare the received triangle carrier signal and the received sine wave signal, and output at least one control signal based on a result of the comparison. The control signal controls an inverter (104) that applies pulse width modulation to a DC power for converting the DC power to a multi-phase power, AC harmonics of the multi-phase power filtered by a common mode inductor.
