In recent years, the development of new technologies is requiring power supplies with wide dc conversion range. In this paper an alternative solution is presented, the properties of the new soft- single-switched (SSS) Boost converter with voltage ratio that are quadratically dependent on duty cycle are discussed. The converter is a zero-current-switching (ZCS) during the turn-on period and a zero-voltage-switching (ZVS) during the turn-off period. The operating principle of the proposed converter is explained; its operating modes along with key waveforms are shown. Moreover, a complete simulation and experimental results have verified the feasibility of its applications in renewable energy systems.
