Abstract: A system and method for generating a digital pulse width modulation (PWM) control signal for a power transfer device that includes providing a digital PWM signal having a stochastic characteristic, and transforming the digital PWM signal to include control information. A digital reference signal having a stochastic characteristic may be used to provide the PWM signal with stochastic characteristics, and the PWM signal is transformed so as not to lose the stochastic characteristic and stored in a digital storage device. The stored PWM signal exhibits frequency domain characteristics and is configured to minimize undesirable characteristics such as harmonic signatures, audible noise, component vibration, and frequency-domain energy peaks.
