The rapid consumption of fossil fuel and increased environmental damage caused by it have
given a strong impetus to the growth and development of fuel-efficient vehicles. Hybrid …

Impedance networks cover the entire of electric power conversion from dc (converter,
rectifier), ac (inverter), to phase and frequency conversion (ac-ac) in a wide range of …

Impedance-source networks cover the entire spectrum of electric power conversion
applications (dc-dc, dc-ac, ac-dc, ac-ac) controlled and modulated by different modulation …

This paper extends the impedance-source (Z-source) inverters concept to the transformer-
based Z-source (trans-Z-source) inverters. The original Z-source inverter (ZSI) employs an …

The current and emerging investigations on Z-source/quasi-Z-source inverters (ZSIs/qZSIs)
are presented. The ZSI/qZSI fulfills buck/boost capability in single-stage topology and …

Z-source inverters have become a research hotspot because of their single-stage buck-
boost inversion ability, and better immunity to EMI noises. However, their boost gains are …

To solve the problem of the mismatched voltage levels between the dynamic lower voltage
of the fuel cell stack and the required constant higher voltage (400 V) of the dc-link bus of the …

This paper presents a new single-phase switched-coupled-inductor dc-ac inverter featuring
higher voltage gain than the existing single-phase qZ-source and semi-Z-source inverters …

Z-source inverters are a new class of inverters proposed with output voltage or current buck-
boost ability. Despite their general attractiveness, there are some present limitations faced …

The recently proposed current-fed quasi-Z-source inverter (QZSI) can buck and boost
voltage and provide bidirectional power flow. A crucial criterion for the size of three-phase …
