An Asymmetrical Interleaved Dc-dc Boost Converter for High Step up Applications
نویسندگان
چکیده
A new high step-up converter is projected for a photovoltaic system. An asymmetrical interleaved high step-up converter achieves high step up gain through a voltage multiplier module. The voltage multiplier module is organised by a conventional boost converter and coupled inductors. A conventional boost converter is incorporated to achieve a considerably higher voltage conversion ratio. This configuration reduces the current stress through each power switch. And also constrains the input current ripple, which decreases the conduction losses of MOSFETs. Since the energy stored in leakage inductances is recycled to the output terminal, the efficiency of the system is improved.
