Abstract:
Drive circuits for parallel electric motors are provided. A drive circuit includes an inverter, at least one current sensor, and a DSP. The inverter is coupled to and configured to provide three phase power to a plurality of parallel electric motors. The at least one current sensor is coupled to the inverter and is configured to measure stator phase currents output by the inverter for driving the plurality of parallel electric motors. The DSP is coupled to the inverter and the at least one current sensor and is configured to receive the stator phase currents from the at least one current sensor, and generate at least one PWM signal for controlling the inverter based on the stator phase currents.
