본 고안은 이러한 점을 감안한 것으로, 메인 바테리를 충전시키는 바테리 충전기와 보조 바테리를 충전시키는 DC-DC컨버터를 하나의 모듈로 구현함으로써 시스템의 간략화 및 신뢰성을 향상시킬 수 있도록 한 전기 자동차용 일체형 컨버터를 제공함에 그 목적이 있다.The present invention has been made in view of the above-mentioned problems, and an integrated converter for an electric vehicle that can improve the system simplification and reliability by implementing a battery charger for charging the main battery and a DC-DC converter for charging the auxiliary battery as a single module. The purpose is to provide.

이러한 목적을 달성하기 위한 본 고안에 따른 전기 자동차용 일체형 컨버터는 제1 릴레이는 충전모드시 정류부에 AC전압원으로 부터의 AC전압을 공급하며, 제어부는 충전모드 또는 DC-DC컨버터 모드로의 동작을 판단하여 그에 맞게 시스템 각부를 제어하며, 제2, 제3 릴레이는 상기 제어부의 제어에 따라 스위칭되어 차가 운행하지 않는 경우 상기 정류부의 출력이 메인 바테리에 충전되거나 주행시 메인 바테리의 전압이 보조 바테리에 충전되도록 함을 특징으로 한다.In the integrated converter for an electric vehicle according to the present invention for achieving the above object, the first relay supplies the AC voltage from the AC voltage source to the rectifier in the charging mode, and the control unit operates in the charging mode or the DC-DC converter mode. Determine and control each part accordingly, and the second and third relays are switched under the control of the controller and when the vehicle is not driven, the output of the rectifier is charged to the main battery or the voltage of the main battery is charged to the auxiliary battery when driving.

The first relay 12 and the output of the first relay 12 for switching an AC voltage from an AC voltage source to a rear stage are shown in FIG. The control unit 13 for determining the operation of the rectifying rectifier 11, the charging mode or the DC-DC converter mode to control the system parts according to the rectifying unit 11, the output of the rectifying unit 11 is switched under the control of the control unit 13 The second relay 14 for supplying the main battery or the voltage of the main battery to the auxiliary battery, the second charging according to the operation in the battery charging mode or the DC-DC converter mode under the control of the control unit 13 The output filter unit 16 is switched under the control of the topology 15 and the output filter unit 16 and the control unit 13 for outputting a voltage input through the relay 14 as a voltage required for the main battery or the auxiliary battery. ) The third relay 17 is configured to supply an output voltage input through the main battery or the auxiliary battery.

상기와 같이 구성된 본 고안에서 제어부(13)는 키 오프 상태 즉, 차가 주행중이 아님을 확인하면 충전모드에 맞게 시스템 각부의 동작을 제어하게 된다.In the present invention configured as described above, the control unit 13 controls the operation of each part of the system according to the charging mode when it is determined that the key off state, that is, the vehicle is not driving.

The main battery is charged via the relay 17.

한편, 제어부(13)는 키 온여부를 확인하면 즉, 주행중임을 확인하면 DC-DC컨버터 모드로 동작하도록 시스템 각부를 제어한다.On the other hand, the control unit 13 controls each part of the system to operate in the DC-DC converter mode when checking whether the key is on, that is, driving.

그리고 상기 제2 릴레이(14)는 오프상태이면 단자(①, ②)로 스위칭되며 단자(①, ②)는 각각 메인 바테리의 +,-단자에 접속된다.When the second relay 14 is in an off state, the second relay 14 is switched to terminals ① and ②, and the terminals ① and ② are connected to the + and − terminals of the main battery, respectively.

또한, 제어부(13)는 상기 각 릴레이(12), (14), (17)의 제어와 함께 토폴로지(15)에 보조 바테리(12V)를 충전시키라는 명령을 준다. 이에 따라 토폴로지(15)가 동작하게 되며, 상기 제2 릴레이(14)을 통하여 메인 바테리의 전압이 토폴로지(15) 및 출력 필터부(16)를 거쳐 제3 릴레이(17)로 입력된다.In addition, the control unit 13 commands the topology 15 to charge the auxiliary battery 12V with the control of each of the relays 12, 14, and 17. Accordingly, the topology 15 operates, and the voltage of the main battery is input to the third relay 17 through the topology 15 and the output filter unit 16 through the second relay 14.
