“A Dc Motor Drive”

Abstract: A DC motor drive (100) including power electronics (120) and control electronics (130). The power electronics (120) are arranged to receive a high voltage power supply and to controllably output that supply to a DC motor to controllably operate the motor. The control electronics (130) are arranged to receive a low voltage power supply and to control operation of the power electronics (120) and hence of the motor at least partly in response to signals received by the control electronics (130) indicative of at least one potential difference across the power electronics (120). The drive further includes a microprocessor (150) and an opto-coupler (170) arranged to sense the output of the power electronics (120) and to generate based thereon the signals in a form for optical transmission via opto-coupler (170) between the output of the power electronics (120) and the control electronics (130), .....
