Abstract
A system and method for executing random pulse width modulation in electronic power converters. In accordance with this invention, the sampling period of sampling cycles for pulse width modulation remains constant while the period of switching cycles are varied. The periods of switching cycles are varied using random numbers to calculate delays between the start of coincident sampling and switching cycles.
