In this article, a modified transformer interleaving winding technique is implemented to reduce Skin, Proximity and leakage inductance which are associated with high voltage and high frequency, and the proposed techniques are implemented in a proto type of 220W dc-dc converter designed with RCD forward converter topology with current mode control.Abstract:
This paper addresses design issues involved in development of high voltage DC-DC converters such as optimizing isolation transformer parameters (leakage, proximity and Skin Effect), Power MOSFET losses and achieving tight voltage regulation (0.1%) used in Transmit Receive Multi Modules (TRMM). A modified transformer interleaving winding technique is implemented to reduce Skin, Proximity and leakage inductance which are associated with high voltage and high frequency. The proposed techniques are implemented in a proto type of 220W dc-dc converter designed with RCD forward converter topology with current mode control. Silicon Carbide (SiC) MOSFETS are used to improve efficiency of converter. 220W dc-dc converter is having the features of very good regulation ( 75%) in all operating conditions and meets MIL-STD-704E/F. The proto is developed in dimensions of 125mm×60mm.read more
