Assignee:

Thor Power Corporation - Allentown PA

International Classification:

H02P 7/00

US Classification:

318432, 318700, 318807

Abstract:

An electronic control circuit for a brushless motor has an input power circuit providing a DC voltage and a microcontroller integrated circuit receiving the DC voltage. The microcontroller integrated circuit provides three-phase control signals according to a space vector control method. A microprocessor connected to the microcontroller integrated circuit executes supervisory control over the electronic control circuit. An inverter circuit receives the three-phase control signals from the microcontroller integrated circuit and provides driving signals to the brushless motor based on the three-phase control signals received from the microcontroller integrated circuit.

International Classification:

H02P 6/14

US Classification:

31840026

Abstract:

An inverter circuit for a brushless motor utilizes an IPM integrated circuit module. The module includes insulated gate bipolar transistors and has outputs for providing driving signals to the brushless motor based on control signals received at inputs from a microcontroller. A sensing circuit measures the current at the lines from the outputs of the IPM integrated circuit module to the motor. A feedback circuit processes the current measurements and provides signals corresponding to the measured current to the microcontroller.
