본 고안은 충전에 따라 전지를 계속 사용할 수 있게 하는 전지충전회로에 관한 것으로, 특히 피충전용전지의 갯수를 조절할 수 있게 할 뿐만 아니라 충전이 완료되었을때 자동적으로 충전을 정지시키게 한 가변식 전지충전회로에 관한 것이다.The present invention relates to a battery charging circuit that can continue to use the battery according to the charge, in particular variable battery charging that not only can control the number of batteries to be charged, but also automatically stop charging when the charge is completed It is about a circuit.

종래의 전지충전회로에 있어서는 고정된 갯수의 피충전용 전지만이 충전가능토록 되어 있어 다양한 갯수의 피충전용전지에 다양하게 적용할 수 없는 단점이 있었고, 충전이 완료되었을 때 자동으로 충전이 정지되지 않고 계속 충전을 하게 되어 있어 전지의 특성을 열화시키는 단점이 있었으며, 특별히 충전완료시 자동으로 충전이 정지되는 회로가 있었으나 이는 특수한 전지, 즉 급속 충전이 가능한 일부 특수전지에만 제한되어 사용되는 단점이 있었다.In the conventional battery charging circuit, only a fixed number of batteries to be charged are allowed to be charged, and thus, there is a disadvantage that they cannot be variously applied to various numbers of batteries for charging, and charging is automatically stopped when charging is completed. There was a drawback of deteriorating the characteristics of the battery because it was not charged continuously, and there was a circuit that automatically stopped charging when the charging was completed. there was.

본 고안은 이와 같은 종래의 단점을 감안하여, 보통 사용하고 있는 모든 재충전용전지에 대하여 피충전용전지의 갯수에 상관없이 충전이 가능하게 함은 물론, 충전이 완료되면 자동으로 충전이 정지되게 하여 전지를 보호하고, 충전완료시에는 충전완료를 알리는 발광다이오드를 발광시킴으로써 충전 완료여부를 간편하게 알 수 있도록 안출한 것으로 첨부한 도면에 의하여 이를 상세히 설명하면 다음과 같다.In view of the above disadvantages, the present invention enables charging regardless of the number of rechargeable batteries for all rechargeable batteries that are normally used, and automatically stops charging when charging is completed. Protecting the battery, and when the charge is complete, the light emitting diode to inform the completion of the charge by emitting a light so that you can easily know whether the completion of the charge as described in detail by the accompanying drawings as follows.

전원단자(AC)는 전원트랜스(T1)의 일차코일(T11)에 접속하고, 그의 이차코일 (T12)은 다이오드(D1), 저항(R1)을 통한 후, 어드저스터블 프리시젼 션트 레귤레이터 ( Adjustable Pracision Shunt Regulator) (IC1)의 애노드에 접속함과 아울러 저항(R1)을 통해 상기 션트 레귤레이터(IC1)의 게이트에 접속하고,그 접속점은 가변저항(VR2)을 통해 그의 캐소드에 접속함과 아울러 다이리스터(SCR1) 및 발광다이오드(LED1)를 통해 피충전용전지(E1)에 접속하며, 상기 션트 레귤레이터(IC1)의 캐소드는 저항(R2) 및 다이오드(D2)를 통해 상기 다이리스터(SCR1)의 게이트에 접속하고, 상기 발광다이오드 (LED1)와 피충전용전지(E1)의 접속점은 저항(R3) 및 가변저항(VR1)의 가변단자를 통한 후 콘덴서(C1), 다이오드(D3) (D4) 및 저항(R4)을 통해, 애노드가 상기 저항(R2)과 다이오드(D2)의 접속점에 접속된 다이리스터(SCR2)의 게이트에 접속하여 그 다이리스터 (SCR2)를 발광다이오드(LED2)에 접속하여 구성한 것으로 이의 작용 및 효과를 상세히 설명하면 다음과 같다.The power supply terminal AC is connected to the primary coil T 11 of the power supply transformer T 1 , and the secondary coil T 12 is through the diode D 1 and the resistor R 1 , and then the adjustable precision It is connected to the anode of the adjustable practition shunt regulator (IC 1 ), and is connected to the gate of the shunt regulator (IC 1 ) through a resistor (R 1 ), the connection point of which is connected to the variable resistor (VR 2 ). connected to its cathode also the addition die cathode of the thyristor (SCR 1) and the light emitting diode and connected to avoid charging the battery (E 1) through (LED 1), wherein the shunt regulator (IC 1) is a resistance (R 2) and The diode D 2 is connected to the gate of the thyristor SCR 1 , and a connection point between the light emitting diode LED 1 and the battery E 1 to be charged is a resistor R 3 and a variable resistor VR 1. ) capacitor (C 1) and then through a variable terminal of a diode (D 3) (D 4) and via a resistor (R 4), the anode is the resistance (R 2) A diode (D 2) a thyristor (SCR 2) connected to the gate of the will be described the thyristor (SCR 2) a light-emitting diode in detail the operation and an advantage thereof that is configured to connect to the (LED 2) connected to the connection point of the following same.

전원단자(AC)를 통해 전원이 인가되어 트랜스(T1)의 일차코일(T11)에 인가되면, 트랜스(T1)의 이차코일(T12)를 통해 유기된 전원은 다이오드(D1) 및 저항(R1)을 통해 반파정류된 후 어드저스터블 프리시젼 션트 레귤레이터(IC1)를 통해 그의 양단간의 전위차가 일정하게 조정되어 다이리스터(SCR1)의 애노드에 인가됨과 아울러 저항(R2) 및 다이오드(D2)를 통해 상기 다이리스터(SCR1)의 게이트에 인가되어 그가 온되고, 이에 따라 상기 정류전원이 다이리스터(SCR1) 및 발광다이오드(LED1)를 통해 피충전용전지(E1)에 인가되어 전지의 충전이 이루어지게 되며, 이때 발광다이오드 (LED1)가 발광하게 되어 충전상태임을 알 수 있게 된다.When the power source via the power supply terminal (AC) is applied is applied to the primary coil (T 11) of the transformer (T 1), the power Organic through the secondary coils (T 12) of the transformer (T 1) is a diode (D 1) And a half-wave rectified through the resistor R 1 , followed by an adjustable potential shunt regulator IC 1 to uniformly adjust the potential difference between both ends thereof to be applied to the anode of the die thyristor SCR 1 , as well as the resistor R 2 . And a diode (D 2 ) applied to the gate of the die thyristor (SCR 1 ) so that it is turned on, and thus the rectified power is supplied through the die thyristor (SCR 1 ) and the light emitting diode (LED 1 ). E 1 ) is applied to the charging of the battery, at this time, the light emitting diode (LED 1 ) is to emit light it can be seen that the state of charge.

이와 같이 피충전용전지(E1)에 인가되는 전원은 저항(R3) 및 가변저항(VR1)의 가변단자를 통해 콘덴서(C1)에 인가되어 그가 충전되게 되고, 이 충전전원은 다이오드 (D3)(D4)를 통해 다이리스터(SCR2)의 게이트에 인가되어 그가 온되게 된다. 이때 피충전용전지(E1)의 충전이 완료됨과 동시에 콘덴서(C1)의 충전전원이 다이리스터 (SCR2)를 온시키도록 가저항(VR1)의 값을 설정해놓게 되면 피충전용전지(E1)의 충전완료와 동시에 다이리스터(SCR2)가 온되어, 상기 트랜스(T1)로부터 다이오드(D1), 저항(R1), 션트 레귤레이터(IC1) 및 저항(R2)을 통한 전원이 다이리스터(SCR2) 및 발광다이오드(LED2)를 통해 접지 흐르게 되므로, 상기 다이리스터(SCR1)의 게이트에 저전위가 인가되어 그가 오프되고 따라서 충전표시용 발광다이오드(LED1)가 소등됨과 동시에 피충전용전지 (E1)의 충전이 정지되며, 한편 발광다이오드(LED2)는 전류의 흐름에 따라 발광하게 되어 충전이 완료된 상태임을 나타내게 된다.In this way, the power applied to the battery E 1 to be charged is applied to the capacitor C 1 through the variable terminals of the resistor R 3 and the variable resistor VR 1 so that they are charged. It is applied to the gate of the thyristor SCR 2 via (D 3 ) (D 4 ) and it is turned on. At this time, when charging of the battery to be charged (E 1 ) is completed and the value of the resistance (VR 1 ) is set so that the charging power of the capacitor (C 1 ) turns on the thyristor (SCR 2 ). At the same time as charging of E 1 is completed, the thyristor SCR 2 is turned on so that the diode D 1 , the resistor R 1 , the shunt regulator IC 1 , and the resistor R 2 are turned off from the transformer T 1 . Since power through the ground flows through the thyristor (SCR 2 ) and the light emitting diode (LED 2 ), a low potential is applied to the gate of the die thyristor (SCR 1 ) so that it is turned off and thus the charging display light emitting diode (LED 1). At the same time, the charging of the rechargeable battery E 1 is stopped, while the light emitting diode LED 2 emits light according to the flow of current, indicating that the charging is completed.

상기에서 어드저스터블 프리시젼 션트 레귤레이터(IC1)의 원리에 의해 그의 캐소드전압 VB= VA+Vref(1+VR2/R5) (여기서 Vref=2.5V)같이 결정되고 그의 양단의 전위는 2.5V-36V까지 사용가능하므로 가변저항(VR2)를 적절히 조절하면 원하는 전위를 얻어내어 그에 해당되는 용량만큼의 전지를 재충전시킬 수 있게 된다.According to the principle of the adjustable precision shunt regulator (IC 1 ), it is determined as its cathode voltage V B = V A + V ref (1 + VR 2 / R 5 ) (where V ref = 2.5V) and Since the potential can be used up to 2.5V-36V, if the variable resistance VR 2 is properly adjusted, the desired potential can be obtained and the battery can be recharged as much as the corresponding capacity.

이상에서 설명한 바와 같이 본 고안은 피충전용전지를 충전함에 있어서 피충전용전지의 갯수에 따라 자유로이 충전시킬 수 있으며, 그의 충전이 완료되게 되면 자동적으로 충전을 정지시켜 전지를 보호하고, 충전완료지시용 발광다이오드를 발광시킴으로써 충전완료 여부를 간편히 알 수 있는 효과가 있게 된다.As described above, the present invention can be freely charged according to the number of batteries to be charged in charging the battery for charging, and when the charging is completed, the battery is automatically stopped to protect the charge and the charging completion instruction By emitting a light emitting diode for the charge it is possible to easily know whether the charge is complete.
