Patent ID: 7932777

Claim:
Apparatus comprising at least first and second reactive loads, a first circuit means that generates a first switching signal and includes switching elements with respective control terminals, a second circuit means that generates a second switching signal and includes switching elements with respective control terminals, means for generating a first PWM signal that includes a fundamental switching band signal component of the first switching signal and that further includes a baseband signal and for applying said first PWM signal to said control terminals of said first circuit means, means for generating a second PWM signal that includes a fundamental switching band component of the second switching signal that has substantially the same magnitude and phase as the fundamental switching band component of said first PWM signal, and that further includes a baseband signal that is the inverse of said baseband signal that is included in the first PWM signal, and for applying said second PWM signal to said control terminals of said second circuit means, wherein at least one of said reactive loads is a capacitive load.
