Experimental Comparison of the Efficiency, Power Density and Thermal Performance of Two BIPV Converter Prototypes

© 2018 IEEE. This paper presents an experimental comparison between two series resonant full bridge converters for use in BIPV applications. The first converter employs Si MOSFETS and the second converter uses GaN HEMTs for the switches of the full bridge. The practical implementation and design of the boards and the trade-offs between components are highlighted. The efficiency, power density and thermal performance of the converters are discussed in detail. Practical issues, such as secondary oscillatory behaviour, in the development of a phase-shifted full bridge are highlighted. The used transformer is modeled, including all parasitic elements. Several solutions to avoid transient oscillations in the secondary are set forward. To mitigate these high-frequency voltage transient overshoots, the best solution was found to equip the primary of the converter with a series resonant tank.
