N2 - In this paper, a single-switch step-up DC-DC converter based on switched-capacitor (SC) and built-in-transformer (BIT) is proposed. By replacing one active switch in the Ladder switched-capacitor converter (SCC) with the primary side of a BIT and inserting the secondary side of the BIT to the multiplexed current path, the proposed topology integrates the high power-density feature of a Ladder SCC with the voltage-lift effect of a BIT. In addition, the issues of high current spikes and limited high-efficient voltage regulation range of the traditional Ladder SCC are tackled, making it suitable for distributed generation system, micro-grid and so forth. In this paper, a comprehensive analysis of the operation principle, ideal voltage gain, component stress and topology extension is given. A 100W prototype with input 36.4V-73.5V and output 400V is designed, built and tested to demonstrate the validity of the proposed converter.
