Analysis of Active-Network Converter With Coupled Inductors

摘要: High step-up voltage gain dc–dc converters are widely applied in fuel cell stacks, photovoltaic arrays, battery sources, and high intensity discharge lamps power systems. Active-network with coupled inductors (CL-ANC) derived from switched inductor active-network (SL-ANC). The proposed converter contains two which can be integrated into one magnetic core switches. provide a relatively conversion ratio small duty cycle; the current stress of switches low is helpful to reduce losses. This paper shows key waveforms CL-ANC detailed derivation steady-state operation principle. effect leakage inductance on discussed. devices illustrated comparison between SL-ANC given. Finally, prototype has been established lab 200 V 400 V output under different turn ratios. Experimental results given verify correctness analysis.
