본 고안은 정전압 충전기에 관한 것으로, 특히 밧데리에 충전되는 충전전압이 항상 일정한 전압을 유지하도록 하고 또한 밧데리의 과충전을 방지하는 것을 그 특징으로 하고 있다.The present invention relates to a constant voltage charger, and in particular, characterized in that the charging voltage charged in the battery to maintain a constant voltage at all times and to prevent overcharging of the battery.
일반적으로 충전 및 방전의 기능을 갖고 있는 밧데리는 전원이 공급되는 중에 전원을 충전하고 충전이 완료되면 충전을 중단한 상태에서 전원의 공급이 차단될 때를 기다리고 있다가 전원의 공급이 차단되면 충전전원을 서서히 방전시키도록 한 것임은 이미 잘 알려진 사실이다.Generally, the battery which has the function of charging and discharging charges the power while the power is being supplied and waits when the power supply is cut off while the charging is stopped. It is well known that it is to discharge slowly.
지금까지 일반적으로 사용되고 있는 충전기의 경우 밧데리를 규정 충전시간 이상동안 충전시키면 밧데리에 무리가 발생할 수 있었다. 따라서 밧데리가 규정충전 시간동안 충전되면 그 밧데리를 충전기로부터 꺼내 두어야 하는데, 그렇게 하면 자연방전에 의해 밧데리의 충전전압이 낮아져서 밧데리의 사용시간이 짧아진다고 하는 단점을 가지고 있었다.In the case of chargers that have been used so far, if the battery is charged for more than the specified charging time, the battery may be overwhelmed. Therefore, when the battery is charged for a specified charging time, the battery must be taken out of the charger, which has the disadvantage of shortening the usage time of the battery by lowering the charging voltage of the battery by natural discharge.
이에따라 본 고안은 밧데리로 공급되는 충전전원이 항상 일정하게 공급되면서 밧데리의 과충전도 방지토록한 정전압 충전기를 제공하는 것을 그 목적으로 한다.Accordingly, an object of the present invention is to provide a constant voltage charger to prevent the battery from overcharging while the charging power supplied to the battery is constantly supplied.
이와같은 목적을 달성하기 위한 본 고안은 트랜스에 의해 일정하게 전압 강하된 AC전원은 브릿지 다이오드를 거치면서 DC전원으로 변환되고, 이 DC전원은 정전압 다이오드를 거쳐 비교기로 입력 되도록 하면서 상기 비교기에는 이의 출력에 의해 동작하는 스위치 트랜지스터를 경유하여 밧데리로 공급되는 전원이 기준전압으로 인가되도록 함으로써 밧데리에 충전이 완료될 때까지 일정한 충전전원에 의해 충전되도록 한 것이다.In order to achieve the above object, the present invention provides an AC power source having a constant voltage drop by a transformer, which is converted into a DC power supply via a bridge diode, and the DC power supply is input to a comparator via a constant voltage diode, and its output is provided to the comparator. The power supplied to the battery is applied to the battery via the switch transistor operated by the reference voltage to be charged by a constant charging power until the battery is fully charged.
이하 본 고안을 첨부 도면에 의거 상세히 설명하여 보면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
트랜스(1)의 1차측으로 입력되는 AC전원은 전압의 크기에 따라 2차측 코일을 변화시키는 절환스위치(2)를 거쳐 일정하게 전압강하 되도록 하고, 일정비율로 전압강화된 AC전원은 브릿지 다이오드(3)를 경유하는 중에 DC전원으로 변환된 후 정전압 다이오드(4)를 거쳐 비교기(5)의 비반전 입력단으로 인가되도록 하고, 상기 비교기(5)의 출력단에 베이스가 연결되며 콜렉터로 DC전원을 공급받는 스위칭 트랜지스터(6)의 에미터에는 밧데리(7)를 접소가여 충전 전원이 흐르도록 하는 동시에 상기 비교기(5)의 반전입력단에 기준전압으로 인가 되도록 한 것이다.AC power input to the primary side of the transformer (1) is to be a constant voltage drop through the switching switch (2) to change the secondary coil in accordance with the magnitude of the voltage, AC power which is voltage-enhanced at a constant ratio bridge bridge ( 3) after being converted to DC power supply via the constant voltage diode (4) to be applied to the non-inverting input terminal of the comparator 5, the base is connected to the output terminal of the comparator 5 and supplies the DC power to the collector The emitter of the switching transistor 6 receives the battery 7 so that charging power flows and is applied as a reference voltage to the inverting input terminal of the comparator 5.
이와같이 구성한 본 고안의 정전압 충전기는 입력되는 AC전원에 따라 절환스위치(2)를 조절하면서 트랜스(1)에 의해 일정한 AC전원으로 전압 강화된 후 브릿지 다이오드(3)를 거치면서 DC전원으로 변환되도록 한다.The constant voltage charger of the present invention configured as described above is voltage-enhanced by a transformer (1) to a constant AC power while controlling the switching switch (2) according to the input AC power to be converted to DC power through the bridge diode (3). .
DC전원은 정전압 다이오드(4)를 거치면서 항상 일정한 전압으로 비교기(5)의 비반전 에 인가되도록 하며 스위칭 트랜지스터(6)의 에미터에 연결된 반전입력단으로 전원이 인가되지 않는 상태에서는 비교기(5)의 출력이 H가 되어 스위칭 트랜지스터(6)를 온시키도록 하고, 스위칭 트랜지스터(6)의 콜렉터-에미터를 통한 DC전원을 밧데리(7)에 일정한 충전전원으로 흐르게 되어 충전이 빨리 이루어지도록 한다.DC power is always applied to the non-inverting of the comparator 5 at a constant voltage through the constant voltage diode (4), the comparator (5) in the state that the power is not applied to the inverting input terminal connected to the emitter of the switching transistor (6) The output of H becomes H to turn on the switching transistor 6, and DC power through the collector-emitter of the switching transistor 6 flows to the battery 7 with a constant charging power so that charging is performed quickly.
밧데리(7)에 충전이 완료되는 동안에는 충전전원으로 인해 비교기(5)의 반전 입력단으로 정전압 다이오드(4)를 통한 전원보다 낮은 전압이 인가되지만 충전이 완료되어 충전전원이 흐르지 않게 되면 스위칭 트랜지스터(6)의 콜렉터-에미터를 통한 DC전원의 비교기(5)의 반전 입력단으로인가되면서 비교기(5)의 출력이 L가 되도록 하여 스위칭 트랜지스터(6)를 오프시키면서 충전이 되지 않게 된다.While charging is completed in the battery 7, a voltage lower than that through the constant voltage diode 4 is applied to the inverting input terminal of the comparator 5 due to the charging power. However, when the charging is completed and the charging power does not flow, the switching transistor 6 The input of the comparator 5 of the DC power supply through the collector-emitter of the () is applied to the inverting input terminal of the comparator 5 so that the output of the comparator 5 becomes L and the charging of the switching transistor 6 is turned off.
그리고 다른 밧데리(7)를 교체하여 충전을 시키고자 하면 전술한 동작에 의해 일정한 충전전원이 흐르면서 빠른 충전이 행하여지게 된다.And if you want to replace the other battery (7) to be charged by the above-described operation, the constant charging power is flowing and fast charging is performed.
