Method for starting boost DC/DC circuits with isolating transformers and apparatus thereof

摘要: A method for starting a boost DC/DC circuit with isolating transformer is provided. charging operation on an output side capacitor achieved through controlling the turn-on and 5 turn-off of four power transistors at input side, process accomplished when voltage across reaches threshold. The may be realized based conventional without modifying structure, no power- consumption component such as resistor added to circuit, thus extra loss produced in process.
