Typical voltage levels from medium-voltage (MV) applications introduce additional challenges to designing the auxiliary power supply (APS) necessary to provide power to the secondary circuits of the main converter. This paper aims to present the design of a 100 W APS for 0.6–2 kV input DC voltage and 24 V output. The selected architecture addresses the medium voltage to low voltage challenge by adopting two stage approach – a simple robust DC transformer (DCX) stage and a low voltage regulation stage. The design of the main building blocks of the APS are described followed by simulation results.
