  • Systems and methods for reducing the magnitude of harmonics produced by a power inverter
    Patent number: 7688605
    Abstract: Systems and methods are provided for operating a pulse width modulation (PWM) circuit in a direct current (DC) to alternating current (AC) power inverter to reduce the magnitude of harmonics. The PWM circuit operates using a reference signal having an irregular period. In one implementation the irregular periodicity includes a sequence of periods uniformly distributed about a target period.
