چکیده مقاله
This paper proposes a new non-isolated single switch boost DC-DC converter for high voltage applications. The proposed converter combines the conventional boost converter with two inductor-capacitor-diode (L-C-D) cells and achieves non-inverting high voltage gain without using a high duty cycle. Additionally, the proposed topology presents a continuous input current that makes it suitable for renewable energy applications, such as photovoltaic systems. The absence of a transformer, using devices with low voltage rating, low voltage stress across the semiconductors, no voltage spike on the switches, and common ground between source and load terminals are advantages of the proposed converter. The principles of the operation in three different modes are analyzed. In addition, the design considerations for the proposed converter are discussed. The main parameters of the converter like the voltage gain and the voltage stress on the diodes and switches are calculated and then compared with other solutions introduced in previous works. Finally, a 400W/200V experimental prototype is designed and experimentally tested. The experimental results demonstrate the effectiveness of the proposed converter.
