Title: Regenerative braking controller employing no-break inverter for dc motor
Inventor: KOCHIYA AKIRA
IPC: H02P3/14
Filed: 1979-06-07
Abstract: PURPOSE:To enable regenerative braking in power failure and improve regeneration efficiency, by using a static Leonard system employing a no-break inverter to control the regenerative braking of a DC motor. CONSTITUTION:Normally, a DC motor 5 is energized by a commercial power source S through switches SW1, SW2 and a static Leonard unit 18 or 19 so the motor is driven. At that time, an inverter 17 is operated synchronously with the commercial power source S and a battery B is charged by a power rectifier 16. Regenerative braking is effected by the AC side of the Leonard unit 18 or 19 through the switch SW2. In power failure, the switch SW1 is opened and the motor 5 is run through the static Leonard unit 18 or 19 by power from the battery B based the inverter 17 already in operation. In the regenerative braking, AC power is supplied from the AC side of the static Leonard unit 18 or 19 to the AC input side of the power rectifier 16 through the switch SW2 to charge the battery B.
