Abstract:
An electric motor controller, an electric motor drive circuit, and methods for combined electric motor control are provided. The drive circuit is configured to drive a first electric motor and a second electric motor. The drive circuit includes a rectifier configured to convert an AC input voltage to a pulsed DC voltage, and a first DC link electrically coupled to the rectifier. The first DC-link includes a low-capacitance capacitor having a capacitance less than 10 μF. The drive circuit also includes a first inverter coupled to the first DC-link, the first inverter configured to generate a conditioned output voltage to drive the first electric motor, a second DC-link electrically coupled to the first DC-link, and a second inverter coupled to the second DC-link. The second inverter is configured to generate a conditioned output voltage to drive the second electric motor.
