This paper presents a design of wide input voltage range 2 kW flyback resonant converter for the wind turbine system. The propose converter design for operated under zero voltage switch, it could increase the efficiency of system by reducing the turn on switching loss. The advantages of this converter can be operated in a wide input voltage range, isolation and used a few devices. From the simulation result with PSpice software and experimentation results are conform together which shows the designed circuit can be operated under zero voltage with high efficiency and wide input voltage range (90-240V), by the simulation results can be used for the specified rate of power semi-conductor devices.
