Constructing A Novel Power Converter by Matrix Converter Theory and Z-Source Inverter Concepts for ISA 42 V PowerNet System

Abstract

This paper proposes a new converter for the 42V ISA system. The problem of the low voltage rating of the AC machine developing regulated 42V with input power factor correction has bee addressed in this paper. The proposed converter uses a matrix converter coupled with a z-source inverter, achieving boost mode operation DC-AC conversion and buck AC-DC operation, and allowing the peak voltage of the AC motor to exceed the 42V DC bus voltage substantially. The AC side operates with near unity power factor in generating operation. The paper investigates the quadrant operation of the converter, its control, and its steady-state and open-loop dynamic performance.

Single-Phase Voltage-Fed Z-Source Matrix Converter

“…Several papers on Z-source matrix converters have been published in recent years [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Several are based on the Z-source inverter topology [7][8][9]，one is based on the ac-ac cycloconverter concept [10], several are based on the concept of combining the Z-source ac-ac converter with a traditional matrix converter [11][12][13][14][15][16][17], and several describe the sparse matrix converter based on the Z-source concept and its control method [18][19][20][21]. This paper will analyze and describe the single-phase Z-source matrix converter which is based on the combination of Z-source ac-ac converter and traditional matrix converter topology.…”
