摘要：

为减小ICPT变换器开关损耗以及简化软开关控制电路,引入推挽变压器,通过在变压器输出接发射线圈和补偿电容,使发射线圈与补偿电容构成的谐振网络呈感性来实现零电压开通,开关管漏源极两端并联电容实现零电压关断,从而不需要增加电压过零检测电路和相应的控制电路即可实现软开关。对软开关的工作原理进行了分析,给出了零电压的工作条件以及推挽变压器匝数的边界条件,仿真及实验结果表明该变换器可工作在软开关条件下,具有驱动简单、传输效率高的特点。

Abstract:

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.

Key words: electrical engineering, ICPT converter, push-pull transformer, soft-switching, boundary condition
