CONTROL UNIT FOR ASYNCRONEOUS ELECTRIC MOTORS WITH SHORT-CIRCUITED ROTOR Russian patent published in 2012 - IPC B60L9/16 B60L15/20 H02P27/00 

FIELD: electrical engineering.

SUBSTANCE: this invention covers frequency-regulated drives and can be applied for electrical transport. The control unit contains DC power source unit with unregulated output voltage, DC power filter unit, autonomous voltage inverter units, electric motor units, low-current AC power source unit with regulated output voltage, forming unit of control sinusoidal multiphase DC signals and synchronizer unit. DC power source unit provides DC-AC conversion without DC voltage magnitude regulation at its output. Low-current DC power source unit provides output voltage regulation depending on frequency of the control sinusoidal multiphase AC signals.

EFFECT: reduction of mass and dimensions parameters; increase in reliability and decrease of power consumption by a control unit of asynchronous motor with short-circuited rotor.
