A High-Efficiency Wireless Power Transfer System Using Quasi-Z-Source Inverter and Current-Double Synchronous Rectifier for Low-Voltage and High-Current Applications

IEEE Transactions on Transportation Electrification, 2022
In low-voltage and high-current wireless power transfer system (LVHC WPTS), the loss of power loop is usually large due to the high-current. More critically, the equivalent load resistance (ELR) is usually much lower than the optimal load resistance ...

Dual Active-Switched-Capacitor Quasi-Z-Source Inverter

2019 IEEE Conference on Energy Conversion (CENCON), 2019
This paper proposed a new qZSI topology called dual active-switched-capacitor qZSI (DASC-qZSI). This new proposed topology offers high voltage gain and boost factor value by using less components. In this paper, the proposed topology will be analyzed and compared with previous high boost qZSI topology.

A new topology for quasi-Z-source inverter

2015 30th International Power System Conference (PSC), 2015
In this paper, a new circuit is proposed for step-up Z-source inverter based on QZSI (quasi-Z-source inverter). The proposed topology inherits all advantages of the conventional topology. The proposed topology in comparison with conventional topology reduces the ST (Shoot-through) duty cycle by over 25% at the same voltage boost factor.
