System and method of commonly controlling power converters
First Claim
1. A power system for controlling power transfers to an electric machine, comprising:
- an alternating current/direct current (AC/DC) power converter operable to convert alternating current (AC) power received from the electric machine into direct current (DC) power when the electric machine is operating as a generator, and operable to convert received DC power from at least one DC power source into AC power when the electric machine is operating as a motor;
at least one direct current/direct current (DC/DC) power converter operable to convert a low DC voltage to a high DC voltage; and
a multi-converter system controller operable to control the AC/DC power converter and the DC/DC power converter.
