This Paper is concerned on developing DC-DC converter using ZVS-FB-PWM Converter. The converter output is 28V and regulated by phase shift control methode. MOSFET is used by the main switching device and high frequency transfomer is made for operating at 300kHz swiching frequency When the load vary widely, converter's ZVS characteristic is expressed by experiment result

This paper describes a design method of grid-connected photovoltaic power generation systems with three phase inverter. A 3-phase 50 kW photovoltaic power generation system including a DC/ AC inverter is designed and made m order to<br/> investigate. the system performance for grid connection. Also the control scheme of a three phase current-controlled PWM inverter is presented by using d-q transformation. The experimental waveforms show that the proposed system has stable behavior with an unit power factor in<br/> utility-interactive operation.
