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.

With exten-sion from the basic dc–dc converters, a series of ac–ac converters such as buck, boost, buck-boost, Cúk, and isolated converters are obtained. By PWM duty ...

However, most of the researches are focused on high power AC-DC and DC-AC applications. This paper presents several multilevel DC-DC converters, which can be used in automotive applications as well as in high power applications. Based on the diode-clamp, flying-capacitor, and cascaded multilevel inverters, their correlative DC-DC converters are derived. A 1 kW prototype of four-level flying-capacitor DC-DC converter used in automotive systems was built as an example to demonstrate the advantages.

These circuits have a limitation: high pulse cur-rents will occur at the switching transients, which will reduce the efficiency and cause ...
