Abstract :
The actively clamped resonant DC link inverter (ACRLI) is a well established soft-switching topology, however its resonant inductor is problematic, and is often cited as its primary stumbling block. This paper presents the design and fabrication of a very-low-loss high frequency ACRLI optimised inductor. The low-loss design was obtained by minimising the hysteretic and eddy current loss of the inductor´s ferrite cores, and the conduction loss of the Litz wire windings. The inductor was built, including custom Litz wire, with a resulting loss of less than 16 watts, or 0.16% of the total 10 kW inverter throughput. This represents a significant improvement in the current state of the art in ACRLI inductor design and extends the applicability of the ACRLI topology
