| Abstract: | Input-series and output-parallel(ISOP) converter can reduce the voltage stress of switches connected to the primary coil of transformers and reduce the peak current of switches connected to the secondary coil of these trans-formers,so it is suitable for the high input voltage and high output current conversion application.An ISOP current mode AC converter and its control strategy are proposed.Their operate principles are investigated.The control strategy ensures the voltage sharing of input divided capacitors and the current sharing of output current of the converter.By prototype experiment,the correctness of operate principle and control strategy of this converter are proved. |
