The present invention relates to a regenerative braking system for an electric vehicle, which can additionally recover more power when a pulse width modulation signal is switched off during regenerative braking, thereby enabling continuous and constant regenerative braking. The regenerative braking system comprises: an electric motor (10); a battery (20) connected to the electric motor (10); a rotation driving unit (30) connected between the electric motor (10) and the battery (20); a regenerative braking unit (40) connected between the electric motor (10) and the battery (20); a constant regenerative braking unit (50) connected between the electric motor (10) and the battery (20) to constantly recover electricity while being turned on when the regenerative braking unit (40) is turned off, constantly charging the battery (20); and a controller (60) connected to all devices including the rotation driving unit (30) to control the same.

    본 발명은 회생 제동시 펄스폭변조 신호의 오프타임에 보조적으로 전력을 더 회수하여 연속적이면서 상시적으로 회생 제동이 이루어질 수 있도록 하는 전기자동차용 회생 제동 시스템에 관한 것으로, 본 회생 제동 시스템은 전기모터(10)와, 상기 전기모터(10)에 연결되는 배터리(20)와, 상기 전기모터(10)와 배터리(20) 사이에 연결되는 회전구동부(30)와, 상기 전기모터(10)와 배터리(20) 사이에 연결되는 회생제동부(40)와, 상기 전기모터(10)와 배터리(20) 사이에 연결되어 상기 회생제동부(40)의 오프타임시에 온타임되면서 상시적으로 전기를 회수하여 상기 배터리(20)를 상시적으로 충전할 수 있도록 하는 상시회생제동부(50)와, 상기 회전구동부(30)를 포함하는 제반 기기에 연결되어 이들을 제어하는 컨트롤러(60)를 포함한다.
