A high gain noninverting DC–DC converter with low voltage stress for industrial applications

A noninverting DC–DC converter with high voltage gain and low voltage stress on the switches for industrial applications is proposed in this research article. The proposed converter has used a voltage multiplier cell twice in the circuit that gives the proposed converter a symmetrical configuration and provides low voltage stress across both the switches. The symmetrical configuration of the proposed converter makes it easier to select the components. The proposed converter provides a voltage gain that is more than three times of the conventional boost converter. A 200-W hardware prototype of the proposed converter has been developed and tested under continuous conduction for static and dynamic conditions. The power loss analysis is done using PLECS software by incorporating the real parameters of switches and diodes from the datasheet. The converter performance is found to be good in open-loop conditions and is in agreement with the theoretical analysis.
