Abstract
A pulse width modulation circuit (10) has a first set of windings with a first inverter circuit coupled thereto and a second set of windings having a second inverter circuit coupled thereto. A pulse width modulation controller pulse width modulates the first inverter circuit and the second inverter circuit so that the first inverter circuit has a predetermined phase shift therebetween to reduce input ripple.
