A dynamically selectable multimode pulse width modulation system includes ramp generator means for generating a ramp; pulse edge modulation means responsive to the ramp generator means for defining a leading edge modulated pulse, a trailing edge modulated pulse and a dual edge modulated pulse; and mode selection means responsive to the pulse edge modulation means for selecting one of the leading edge modulation, trailing edge modulation, and dual edge modulation modes of pulse width modulation.
