  • Active clamp full bridge converter and driving method thereof
    Patent number: 10277138
    Abstract: Provided is an active clamp full bridge converter, which includes: a transformer having a primary coil and a secondary coil and configured to convert a voltage; a primary circuit connected to an input capacitor for supplying an input power and including a full bridge circuit having first to fourth switches to transmit the input power to the primary coil according to a switching operation of the first to fourth switches; and a secondary circuit connected to the secondary coil and including a rectifying bridge circuit having first to fourth diodes, an active clamp circuit connected to the rectifying bridge circuit and composed of an active clamp switch and a clamping capacitor connected in series, and an output inductor connected to the active clamp circuit, to transmit an energy received from the primary circuit by the transformer to an output capacitor connected to the output inductor and the active clamp circuit.
