Abstract

See full text

A control circuit for an electric motor includes low and high voltage subcircuits, and an isolation barrier therebetween. The low voltage subcircuit comprises a current controller configured to generate a driving signal, and a feedback loop. The high voltage subcircuit comprises a power bridge configured to output a current that drives the motor, a current sensor configured to measure the current, an analog front-end and an analog-to-digital converter (ADC). The analog front-end is configured to apply as a function of the measured current. The isolation barrier comprises an isolator having: first and second channels to pass respectively a clock signal and a control signal from the low to high voltage subcircuit to select the gain; and third and fourth channels to pass respectively an output signal of the ADC and a replica of the clock signal from the high to low voltage subcircuit.
