Abstract: High-frequency transformer isolated DC-to-DC converters are widely used for power conversion in alternate energy and other applications. In such applications, it is important for the converter to operate with wide variations in input voltage. A hybrid phase modulated converter (HPMC) can achieve this with soft-switching characteristics. This paper presents the analysis of such a hybrid phase modulated DC-to-DC converter for different modes of operation. A systematic design procedure is illustrated with a design example. PSIM simulation results obtained for the design example are presented for varying input voltage and load conditions. A 200 W experimental converter with 22 to 41 V input and 350 V output switching at 100 kHz, has been built to verify the performance of the designed converter.
