Cascadable Enhanced Quasi‐Z‐Source Inverter with Reduced Current Stress

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
A new magnetically coupled impedance source (MCIS) inverter with a clamped DC‐link voltage is proposed. ABSTRACT In magnetically coupled impedance source (MCIS) inverters, the turn ratio of the coupled inductor offers design flexibility. The leakage inductance, however, poses additional challenges, mainly voltage spikes.

A New Fully Soft‐Switching High Step‐Up Interleaved Converter for Optimal Efficiency

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
A novel fully soft‐switching interleaved high step‐up converter is proposed, incorporating coupled inductors and a voltage multiplier cell to achieve high voltage gain and improved efficiency. Soft‐switching is realized through zero voltage switching (ZVS) for the main switches and zero current switching (ZCS) for the auxiliary switch.
