Motor system, has gate driver unit electrically connected with optocoupler switch, power unit electrically connected with driver unit and fed with direct current, and motor electrically connected with power unit

摘要

The system has two converters fed with alternating current and outputting two direct currents (DCs). A microcontroller (20) is fed with one DC for operating the microcontroller. An optocoupler switch (26) is electrically connected with the controller and is fed with the other DC for operating the switch. A gate driver unit (32) is electrically connected with the switch and is fed with the latter DC for operating the driver. A power unit (28) is electrically connected with the driver unit and is fed with the latter DC. A motor (30) is electrically connected with the power unit.
