Soft-Switched High Step-Up Quasi Z-Source Converter With Low Switch Voltage Stress

IEEE transactions on industrial electronics (1982. Print)
In this article, a fully soft-switched high step-up quasi-Z-source (qZs) converter with low switch voltage stress is proposed. In this converter, switched capacitor and coupled inductor techniques are combined with the basic qZs structure to attain high ...

Comparative Evaluation of Three Z-Source/Quasi-Z-Source Indirect Matrix Converters

IEEE Transactions on Industrial Electronics, 2015
Conventional matrix converters (MCs) have limited voltage gain that is less than 0.866, whether for direct MC (DMC) or indirect MC (IMC). Existing Z-source (ZS)/discontinuous quasi-Z-source (qZS) DMCs and ZS IMCs achieved larger than 0.866 voltage gain; however, the former inherited the complex commutation from DMC, and the latter involved a ZS network

A Family of Z-Source Matrix Converters

IEEE Transactions on Industrial Electronics, 2012
This paper extends the Z-source concept to matrix converters and explores a family of Z-source matrix converters. Their principles and characteristics are analyzed, and a simplified voltage-fed Z-source matrix converter is used as an example to demonstrate its operation, voltage gain versus modulation index, PWM method, boost control, and ...

Simplified quasi‐Z source indirect matrix converter

International Journal of Circuit Theory and Applications, 2014
SummaryConventional matrix converters have a limited voltage gain less than 0.866 and also require many power switches and additional input filter that ensures a low input current harmonics to the grid. Quasi‐Z source (qZS) indirect matrix converter can provide high voltage gain and ensure a sinusoidal input current without additional input filter ...

Hybrid Z-Source Boost DC–DC Converters

IEEE Transactions on Industrial Electronics, 2017
This paper presents a new family of hybrid Z-source boost dc–dc converters intended for photovoltaic applications, where the high step-up dc–dc converters are demanded to boost the low-source voltages to a predefined grid voltage. Because the boost capabilities of the traditional Z-source networks are limited, the proposed converters are composed of ...

Matrix converter with a series Z-source

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
Series Z-source network, an expansion of the popular concept of Z-source dc link, was originally proposed for boosting the output voltage of power electronic inverters. In this paper, that idea is extended onto a three-phase indirect matrix converter.

Generalized single phase Z-source matrix converter

2011 IEEE Electrical Power and Energy Conference, 2011
In this paper a novel topology for single phase Z-source matrix converter is presented. Introduced structure has ability of direct ac-ac converting without frequency restriction. This means presented structure can generate wide range of frequency without considering input frequency.
