Abstract
The objective of this paper is the design and measurement based verification of a highly integrated isolated series resonant DC-DC converter with a power density of a boxed volume of around 6.3 kW/l for use in a PV micro-inverter. In addition to modular flexibility and simplified installation, the integration of the inverter into the solar module leads to challenging requirements but can result in higher efficiency compared to conventional inverters. The planar design of the transformer as well as the PCB integrated winding with litz structure allow for a compact prototype and efficient use at high frequencies around 500 kHz. Furthermore, a comparison of the performance of Si and SiC diodes in the rectifier stage was performed and the results are discussed in the paper. A comparison of different operating points provides information on the optimization potential of the individual components, which results in a maximum efficiency of 96.55%.
