ABSTRACT:
The present invention provides a modulation controller for use with a three phase converter. In one embodiment, the modulation controller includes a three phase modulator configured to provide vector control signals for the three phase converter that generate a common mode voltage. Additionally, the modulation controller also includes a transition modifier coupled to the three phase modulator and configured to provide a shaping function for the vector control signals that extends a transition period of the common mode voltage.
