Active clamp flyback inverter considering leakage inductance of transformer for photovoltaic AC modules

In this paper, effects of leakage inductance components in active clamped flyback inverter are analyzed. In this active clamped flyback inverter, the leakage inductance influences on the control time of the active clamp switch, the voltage across the primary switches, and the resonant capacitor selection. Therefore, it is essential to analyze the effects of leakage inductance for design of flyback inverter. The detailed operation principle, theoretical analysis and design consideration are presented. And simulation results are presented to validate the theoretical analysis.
