This paper presents a non-isolated bidirectional softswitching dc-dc converter for DC microgrid energy storage synchronization. To assist the soft switching of switches and diodes, the LCL resonant circuit is applied and an input end halfbridge boost converter is enforced. Using the voltage doubler circuit introduced on the output side, a voltage gain of 2X is achieved. Through the non-isolated circuit, the total voltage gain is obtained. The capacitive divider halves the voltage on the greaterdoi:10.35940/ijrte.e6704.018520 fatcat:hot6rld2arbcvevrjbbydbojvi
