Hybrid PWM control for Z-source matrix converter

2011 IEEE Energy Conversion Congress and Exposition, 2011
This paper proposes four control strategies for Z-source matrix converter: simple maximum boost control, maximum boost control, maximum gain control and hybrid minimum stress control. The maximum gain control can obtain the maximum gain at the same modulation index among all four; and the hybrid minimum voltage stress control can obtain the minimum ...

Three-phase voltage-fed Z-source matrix converter

2011 International Conference on Electrical Machines and Systems, 2011
This paper proposes a novel three-phase ac-ac converter topology based on Z-source concept. It could provide buck-boost function and make the role of frequency changer. Compared with the traditional ac-dc-ac converter, it uses fewer devices and realizes direct ac-ac power conversion, so as to have higher efficiency and better circuit characteristics ...

A novel Z-source dc-dc converter

2008 IEEE International Conference on Industrial Technology, 2008
This paper proposes a novel Z-source dc-dc converter topology. Compared to the existing dc-dc converter circuits, they can reduce in-rush and harmonic current, provide larger range of output dc voltage and improve reliability. It can operate in voltage-fed and current-fed when the place of the source and load is exchanged each other, and it can be ...

Single-phase Z-source PWM AC-AC converters

IEEE Power Electronics Letters, 2005
The letter proposes a new family of simple topologies of single-phase PWM ac-ac converters with a minimal number of switches: voltage-fed Z-source converter and current-fed Z-source converter. By PWM duty-ratio control, they become "solid-state transformers" with a continuously variable turns ratio.

Three-Phase Z-Source AC-AC Converter

2006 12th International Power Electronics and Motion Control Conference, 2006
The paper proposes a novel three-phase Z-source ac-ac converter topology, presents its circuit configuration, operating principle and control method. The proposed ac-ac converter employs a unique LC network to suppress the over-current and surge voltage due to the shoot-through or the open-circuit of the two switches. By controlling the duty cycle, the

Control and modulation techniques of Z-source converter

This chapter presents an overview of control and modulation techniques for Z-source converters (ZSCs) used for electric power conversion. ZSCs are categorized into four main categories: DC/DC converters, DC/AC inverters, AC/AC converters, and AC/DC rectifiers.
