A novel compact DC-DC converter for 42 V systems

This paper presents a compact, efficient, magnetic-less bi-directional DC-DC converter for 42/14 V automotive systems. The proposed converter has no or minimal requirement for magnetic components and can achieve an efficiency of 98%. The main circuit of the DC-DC converter is analyzed and its control scheme is presented in the paper. Simulation results and a 1 kW prototype are used to verify the analysis and to demonstrate the advantages.
