Three-phase electronic inverter for variable speed motor and method of operating same.

摘要

A three-phase electronic inverter for an electric induction motor can operate the latter silently without the generation of magnetorestriction noise where the voltage of the rectifier outputted to the power transistor bridge is controlled by a TRIAC with regulation of the angle of conduction while the power transistor are pulsed in response to the output of a microprocessor through level adapters constituted by operational amplifiers.
