谐振双有源桥

Due to their merits of high efficiency and power density, resonant dual-active-bridge (DAB) inverters are receiving heightened attention in microinverters. However, the existing models of resonant DAB inverters, such as the first harmonic approximation (FHA) model, are nonlinear without any steady-state operating point and suffer from low accuracy. This article first proposes the dynamic phasor mo...
