摘要：
In order to reduce the switching loss of ICPT convertor and simplify the soft-switching control circuit, the push-pull transformer was introduced by connecting the transformer coil and the compensation capacitor on the output of the push-pull transformer. The converter can achieve zero-voltage turn-on by making the transformer coil and the compensation capacitor resonant network to present inductive. It can also achieve zero-voltage turn-off by adding capacitors between the drain and source of the switch. Therefore, there is no need to increase the voltage zero-crossing detection and the corresponding control circuits to achieve soft-switching. The working principle of the soft-switching was analyzed. The zero-voltage conditions and the boundary conditions of the number of turns of the transformer were given. Simulation and experiments show that the convertor can operate in soft switching conditions, with the advantages of simple drive and high transmission efficiency.
