Performance and loss evaluation of a hard and soft switched 2.4 MW, 4 kV to 6 kV isolated DC-DC converter for wind energy application
Paper i proceeding, 2012

In this paper, a hard switched and zero-voltage switching full bridge converter for high power applications are compared in terms of their losses. The important issue in designing these kinds of converters is to manage the converter parasitics. Moreover, evaluating the losses at the high frequency transformer with square wave input is another critical point in designing such a high power density converter. The proposed full bridge converters are designed to convert 4 kV input voltage to 6 kV with rated power of 2.4 MW. The comparison is done for three different frequencies: 500 Hz, 1 kHz and 2 kHz. Also, the simulation results and loss calculations are presented.
