Loss distribution and thermal behaviour of the Y-source converter for a wide power and voltage range

Abstract

Abstract-The Y-source converter is one of the recent proposed impedance source converters. It has some advantages as having a high voltage gain between the input and output voltage sides using very small duty cycle ratios. For many applications, the input voltage needs to be boosted to higher output voltage, such as for fuel cell, battery electric vehicles and renewable energy applications. Understanding the loss distribution and thermal performance is very important in order to be able to design a reliable converter with longer lifetime. In this paper, the loss distribution of a Y-source converter for a wide voltage and power range is presented. The influence of the heat losses generated in the converter is also considered for different analysis. A simulation model is developed and verified experimentally rated at 300 W.
