ABSTRACT:
A pulse width modulation scheme allows the creation of a unipolar pulse width modulated output signal. Two switching circuits (104, 204), preferably different legs of an inverter circuit, can operate to not only modulate an input voltage but also to reverse the polarity of the PWM output signal. Both switching circuits can be configured to accomplish both features, thus the switching load is spread out across all four switches.
