Abstract:
Modern day devices often use an AC source as input even though they are operated with DC voltage. In order to have a suitable and flexible DC output, an AC-DC converter is used. However the conventional converters are not suited for high voltage output without sacrificing conversion efficiency. In this paper a new topology of Hybridized Boost-SEPIC (HBS) converter is proposed. This converter is capable of delivering output voltage as high as 1255V at high conversion efficiency. Maximum power factor of 0.97 and minimum THD of 9.94% is ensured by current mode PI controller.
The need of renewable energy is on the rise especially the use of solar energy. Solar energy usually provides with DC power. In order to harvest solar energy effectively, the HBS converter is also integrated with a three phase inverter, with an LCL filter to provide AC supply.
