摘要: In this paper, a novel multiport CLL resonant converter with phase shift and asymmetrical duty-cycle control is analyzed. The power flow can be maintained the between ports, whereas asymmetric duty cycle manages output voltage at load terminals. Series connected transformers secondary side enable to split in each port reduce stresses on switches compared parallel transformers. Even under unbalanced input conditions, ports managed by central without any need for communication devices. order investigate distribution port, two different isolated dc sources variable are used. operation tested 40, 80, or 120 V inputs, of 200 full 1 kW maximum efficiency 97.4%. experimental results show that proposed controller an appropriate topology sustainable energy platforms, which supplied types sources, such as photovoltaic, fuel cell, wind, so on, various capacities.
