Abstract

This paper proposed a kind of converter with partial power processing characteristics—dual-path power converter （DPPC）. The voltage gain and the efficiency characteristics of DPPC are defined and derived from the structure dimension. Then, the voltage gain and the efficiency characteristics of DPPC with different structures are verified by simulation. Finally, one of the converter structures is selected as the experimental object, and a 2 kW experimental prototype is built to prove the feasibility and efficiency of this converter.

Key words
