Abstract

A mirrored modified hybrid switched inductor high gain dc-dc boost converter is proposed in this paper. In this topology, input voltage source is divided into two equal parts and they are embedded in series with the converter inductors. This leads to a reduction in voltage stress across the capacitors. In addition, two mirrored boost converters with switched inductor are connected to each other. By replacing a switched inductor with the main inductor of the boost converter, the output voltage range is developed. This delivers high voltage gain for the proposed converter. The voltage gain, voltage stress across capacitors and current ripple of inductors of the proposed converter are compared with the conventional boost converter and hybrid switched inductor boost converter. The accuracy and performance of the proposed converter are reconfirmed through comparing simulation results of EMTDC/PSCAD software with the mathematical calculations. The main advantages of the proposed topology are high voltage gain, low voltage and current ripples and particularly low voltage stress on the capacitors.
