Four Novel Embedded Z-Source DC–DC Converters
IEEE Transactions on Power Electronics, 2022This article develops a series of improved Z-source dc–dc converters to realize additional voltage pumping and high power density through two propositions. Proposition 1 develops two improved positive- and negative-connected Z-source dc–dc converters (IPZSC and INZSC), using the same number of components as in the existing voltage pumping Z-source ...

Boost type Partial Power Z-Source Converter
2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC), 2019A modified structure of Z-Source converter as partial power processing (PPP) Z-Source converter is presented which is practically applicable for distributed energy systems such as photovoltaic (PV) systems. With a similar approach the proposed converter is different from basic PPP structure of Z-source converter.

Z-Source Inverter Based on CUK Converter
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018This paper proposes a new three-switch single-phase Z-source inverter (ZSI) based on CUK converter, which is named CUK-based ZSI. This topology has the characteristics of buck-boost capability and dual grounding. In addition, the voltage gain of proposed inverter is higher than those of the single-phase quasi-Z-source and semi-Z-source inverters. Aside

Double input Z-source DC-DC converter
2011 2nd Power Electronics, Drive Systems and Technologies Conference, 2011This paper proposes a double input dc-dc converter based on Z-source converters. In the proposed converter, the input dc voltage can be boosted and also input dc sources can deliver power to the load individually or simultaneously, so combination of a battery with one of the new energy sources such as solar array, wind turbine or fuel cell can be used ...

When realized as a dc-dc converter, the introduced Z-source impedance network must similarly be short-circuited for a certain defined duty ratio per switching period. The basic operating principles therefore remain unchanged, except that the rear-end converter bridge is changed to one suitable for performing dc-dc conversion.

Z-Source AC–AC Converters Solving Commutation Problem
IEEE Transactions on Power Electronics, 2007A new family of Z-source ac-ac converters with buck-boost ability are proposed, including four switches single-phase structure and six switches three-phase structure. New commutation strategies for these converters are proposed and safe commutation can be achieved without snubber circuit.
