Abstract
In this paper using a transformer less step up voltage method is used. Reduced the losses and improved the power quality by using this proposed method. Within the photovoltaic (PV) power-generation marketplace, the ac PV module has shown clear growth. However, a high voltage gain converter is necessary for the module’s grid connection through a direct current –alternate current inverter. In this proposes a converter that employs a suspended active switch to isolate energy from the PV panel when the ac module is OFF; this exacting design protects installers and users from electrical hazards. Without excessive duty ratios and the frequent turns-ratios of a coupled inductor, this converter achieves a step-up voltage-conversion ratio; the leakage inductor energy of the coupled inductor is efficiently to the load. These features explain the module’s high-efficiency performance. The full operating principles continuous, discontinuous, and boundary conduction modes are describe. A 15V input voltage, 300V output voltage model circuit of the proposed converter has been implemented; its maximum efficiency is up to 95.3% and full-load efficiency is 92.3%.
