Abstract:
A power converter is provided. In one aspect, the power converter has a first inverter and a second inverter electrically coupled with one another and with a power bus. First switches of the first inverter are arranged symmetrically with second switches of the second inverter so that, when switched in a pulse width modulated switching scheme, the first switches generate a first common mode signal and the second switches generate a second common mode signal that is one hundred eighty degrees out of phase with the first common mode signal. In another aspect, the power converter includes a buck stage having one or more pairs of symmetrically arranged buck switches that can be controlled to reduce or eliminate common mode electromagnetic interference in the buck stage. The power converter can also include one or more pairs of symmetrically arranged inductors.
