Dual-input LC resonant converter

Aiming at the problems of the complex interface circuit structure and high economic cost in multi-source access systems, a dual input resonant DC-DC converter with simple circuit structure, low cost, high reliability, and high efficiency is provided. Moreover, by adopting the fixed-on time modulation method, the proposed converter can achieve full-range continuous adjustment of output voltage. All fully-controlled switching devices are zero voltage turn-on, and all diodes are zero current turn-off.
