Advancing Energy Solution - Residential Grid Integration with DC-DC Converter

Decentralizing the electric market and adapting new loads such as electric vehicles and direct current (DC) energized loads have brought many developments in conventional grids. This modernization of utility grids has brought many non-conventional energy sources to satisfy energy demand. The operation of the old and new loads available on the utility grid is facilitated by using non-conventional energy sources. To operate these loads, different power converters are utilized. The popularity of DC loads has brought many DC microgrids, which are accompanied by solar and fuel cell sources. Voltage levels at the output of these non-conventional sources are very low compared to the voltage required to drive the loads. Therefore, DC-DC converters are utilized to boost the voltage at the output of the non-conventional sources. This paper discusses a new DC-DC step-up converter for boosting the output voltage from a non-conventional source. The DC-DC boost converter has a high voltage gain ratio, which gives four times the voltage gain at duty cycle 50%. Initially, the improvised boost converter is studied, and the performance of the converter’s behavior is tested. The converter enables the real-time use of voltage-boosting techniques by reducing the voltage stress across the MOSFET. The prototype of the converter is prepared, performance is verified, and it is found that the converter can provide a high gain voltage at the converter’s output.
