Abstract
This paper presents an indirect matrix converter (IMC) topology for hybrid electric vehicle (HEV) application with three-phase and single-phase outputs. The HEV includes mechanical, electrical, control, and electrochemical systems among others. In the mechanical system, a traction motor and a compressor motor are used to drive the HEV. The traction motor and the compressor motor are usually operated as three-phase and single-phase motors, respectively. In this respect, a dual AC-drive system can operate the traction and the compressor motor simultaneously. Furthermore, compared to a conventional dual matrix converter system, the proposed topology can reduce the number of switches that the dual outputs share with a DC-link. The application of this system for HEV has advantages, like long lifetime and reduced volume due to the lack of a DC-link. The proposed control strategy and modulation schemes ensure the sinusoidal input and output waveforms and bidirectional power transmission. The proposed system for the HEV application is verified by simulation and experiments.
Highlights
In recent years, the problems regarding environmental pollution have become a significant issue.In response, researchers have made an effort to study green technologies for environmental conservation
This paper presents a development of system for the hybrid electric vehicle (HEV) application with three-phase and single-phase outputs using the indirect matrix converter (IMC)
IMC without any DC-link capacitor, which is used for power conversion system for the HEV application, is able to control the three-phase traction motor and the single-phase compressor motor simultaneously
Summary
The problems regarding environmental pollution have become a significant issue. General dual AC-drive systems with two inverters and DC-link elements have disadvantages including as low efficiency, high volume and short lifetime [3,4,5,6,7]. IMC without any DC-link capacitor, which is used for power conversion system for the HEV application, is able to control the three-phase traction motor and the. This power conversion system guarantees the long lifetime due to absence of the DC-link energy storage elements. This paper presents an application oriented AC dual output based VSMC where the number of switches is reduced in comparison with the traditional dual drive systems.
