Positive output superlift Luo converter is a recent topology in a DC/ DC converter with a
high voltage transfer gain. The modified soft switching technique for positive output superlift
Luo converter is proposed, designed and simulated to show the mitigation of the limitations of
high voltage gain super lift Luo converter. The modes of operation, equivalent circuit, dynamic
equations and steady state differential equations of the soft switched super lift Luo converter
under different time instants were derived to compute the resonant frequencies. This proposed
converter is simulated with resistive load over a wide range and Soft switching waveforms are
shown.
Key words: Super Lift Luo Converter, Voltage Transfer Gain, Resonant frequency,
Geometric Progression.
