Patent ID: 8237700

Claim:
A method comprising: receiving, at a pulse width modulation (PWM) signal generator, an input PWM signal; and generating, at the PWM signal generator and based on the input PWM signal, multiple output PWM signals that have duty ratios substantially equal to a duty ratio of the input PWM signal and that are synchronized to a synchronization signal and that have predetermined phase-shifts in relation to each other, and such that a PWM cycle of a leading output PWM signal of the multiple output PWM signals is prematurely terminated in response to a synchronization event represented by the synchronization signal so as to result in a prematurely-terminated PWM cycle for the leading output PWM signal and such that the prematurely-terminated PWM cycle is replicated for each non-leading PWM signal of the multiple output PWM signals while maintaining the predetermined phase-shifts between the multiple output PWM signals.
