Abstract
Description
지정된 장소(교류전원 AC 110V/220V가있는곳)를 벗어나 어느곳이나 어느장소에서 밧데리를 충전 할수 있어 충전방식의 불필요함을 줄이고 교류전원(AC: ALTERNATING CURRENT)이 필요치 않으므로 전력 손실을 줄이는데 그 목적이 있다.The battery can be charged at any place and any place beyond the designated place (AC power supply AC 110V / 220V) to reduce the need for charging method and to reduce power loss since AC (Alternating Current) is not needed. There is this.
현재가장 많이 사용 하고 있는 충전방식은 교류전원 AC110V/220V를 입전하여 입력단에서 필터를 통해 잡음을 제거하고 이 전압을 트랜스 포머를 통해 1차측에서 2차측으로 전압을 유기한후 정류 다이오드와 콘덴서를 통해 교류전원을 평활하여 직류전압으로 전력 변환하고 저항을 통해 충전전류를 제어하여 밧데리를 충전하는 방식이다.The most common charging method is the AC power supply AC110V / 220V which removes the noise through the filter at the input terminal, induces the voltage from the primary side to the secondary side through the transformer, and then alternates through the rectifier diode and capacitor. It converts the power into DC voltage by smoothing the power and controls the charging current through the resistor to charge the battery.
본 발명은 이런 종래의 충전방식을 바꾸어 무선주파수(RF)를 안테나를 통해 수신한 다음 이 수신된 고주파를 검파 다이오드를 통해 검파한 다음에 직류전압으로 전력 변환시킨후 밧데리가 요구하는 충전전압으로 승압 시켜 저항을 통해 충전 전류를 제어하여 충전하게 되므로 별도의 충전기가 필요하지 않기 때문에 종래의 충전기로 수시 충전해야 하는 불필요함을 줄일수 있고 교류전원이(AC110V/220V)없어도 되므로 전력 손실을 줄일수 있는 장점이 있다.The present invention changes the conventional charging method, receives the radio frequency (RF) through the antenna, then detects the received high frequency through the detection diode, converts the power into a DC voltage, and then boosts the charge voltage required by the battery. Since it charges by controlling the charging current through a resistor, it does not need a separate charger, so it can reduce the unnecessary need to charge it with a conventional charger and can reduce power loss since there is no AC power supply (AC110V / 220V). There is an advantage.
