In the contemporary world, the share of AC loads is significant; however, the requirement of DC loads is rapidly increasing, particularly in household and industrial applications. The systems in which both the AC and DC loads are installed require a dual converter, acting as either a DC-DC converter or DC-AC converter. The usage of the dual converter becomes more valuable if it can reduce the output voltage or amplify the output voltage that is buck or boost operation. The present investigation proposes a dual converter, which provides a positive gain with a duty ratio of 0 to 0.5 and a negative gain with a duty ratio of 0.5 to 1. For either range, the converter acts as a DC-DC converter or an inverse gain DC-DC converter. In case of both duty ratios are combined, the converter acts as a DC-AC converter. The paper describes AC analysis of the extended gain range converter (modified Johnson converter), validated through MATLAB simulation. A comparative study of the modified Johnson converter is done with a current-fed converter, and some important conclusions are presented.
