Reverse power transmission of two-transformer active clamp forward flyback converter
A two-transformer active clamp forward flyback (ACFF) converter without output inductors is suitable for high output current applications such as low-voltage DC-DC converters (LDCs) in electrified vehicles. This paper presents the reverse power transmission operation of an ACFF converter used Synchronous Rectifier (SR). One of the target applications of the proposed converter is bidirectional LDCs used in electrified vehicles due to its high-power density and cost competitiveness. Operational principles with key voltage and current waveforms are provided, and a detailed analysis of each operating interval is provided, offering guidelines for component selection. Experimental results obtained from a 14 V–600 V hardware prototype verifies the feasibility of operation in practical LDCs.
