We study and describe mostly used traditional simplified circuits for full-bridge Zero Voltage Switching-Dual Active Bridge (ZVS-DAB) converter and deduce their mathematical model. On this basis. we propose a high-frequency (HF) mathematical model. which takes into account conduction loss and HF characteristics of the ZVS-DAB converter model. https://www.roneverhart.com/Boxing-Pop-Vinyl-Figure-Ryan-Garcia-04/
