Apparatus for using an induction motor as an electrical generator.

摘要

The apparatus according to the invention for using an induction motor (2) as an electrical generator is characterized by comprising: - a three-phase impressed voltage inverter (1) for connection to the terminals of the induction motor (2), - a tank capacitor (3) connected to the inverter (1) on the direct current side, and - a control circuit (4) of PID action controlled by the motor output parameter or parameters and acting on the operating frequency of the inverter (1) in order to adjust it to a value less than synchronous frequency and such as to create energy balance between the active power generated and that utilised.
