Abstract
A Novel, Transformer-less DC-DC Converter for high voltage gain (HVG) applications is proposed in this paper. The proposed converter consists of an active switched inductor for HVG with reduced voltage and current stress across the components. The proposed converter has a voltage gain of (3D+1) times than that of the conventional boost converter. The proposed converter uses fewer components and provides HVG with relatively small duty ratios. A good feature of the proposed topology is all the switches and intermediate capacitors have equal voltage stress. The proposed converter can support bidirectional operation with wide duty ratio variations. The working principle and steady-state analysis of this converter is explained in detail. Dynamic modelling of the converter is presented, and both voltage and current control operations can be carried out. To validate the theoretical analysis, detailed simulation results are presented. © 2022 IEEE.
