This paper presents the computer simulation model of a grid to vehicle (G2V) wireless power supply using a single-phase matrix converter (SPMC). The proposed system uses the SPMC that operates as a direct AC-AC converter to convert the supply frequency of 50 Hz to reach 20 kHz output frequency. The use of 20 kHz frequency is suitable for wireless power transfer (WPT) operation in order to obtain higher power transfer efficiency between the transmitter and the receiver parts. An advanced of the proposed circuit topology can solve the conventional system for G2V circuit topology that uses multiple stages of power conversion system, resulting in high power semiconductor losses that could lead to low efficiency. In this work, multiple stages of the conventional "AC-DC-AC" circuits have been reduced to a single power conversion stage by using the SPMC circuit topology. The use of the proposed circuit topology can reduce the number of devices, thus reduce the semiconductor losses. A part of reducing the semiconductor losses, the proposed circuit topology could also improve the power density and efficiency of the power supply system. A computer simulation model using MATLAB/Simulink has been developed to investigate the behavior of the proposed system. Selected simulation results are presented to verify the functionality of the proposed system.

“…Through a study carried out on grid-to-vehicle (G2V) wireless power transfer using SPMC topology, it is realized that the use of SPMC can directly convert AC to AC, eliminating the complexity of conventional AC-DC-AC converter [23]. Currently, there are many research on three phase Matrix Converter nevertheless as for SPMC, although it is an advanced circuit topology, it has only been seen for a very limited or few work.…”

The main objective of this work is to model and simulate DC to DC Boost Converter using Single Phase Matrix Converter (SPMC) topology using MATLAB/Simulink (MLS). The output voltage is controlled by using Pulse Width Modulation (PWM) technique. Four pairs of Insulated Gate Bipolar Transistor (IGBT) is used as the switching device where for each pair, it is located in parallel and opposite direction. Safe commutation technique is performed in preventing voltage spike at the output. Through the simulation, at switching frequency of 25kHz, the model is able to step up its input voltage about two times larger and all of the results achieved a good agreement with the principle of four quadrant operation. It is also realized that without the implementation of safe commutation technique, spikes were generated and the model is unable to boost its input voltage. All of the selected results from the analysis which includes variation of quadrant, switching frequency, duty cycle and resistive load are presented in this paper.

“…Matrix Converters (MC) have been classified as an advanced and emerging converter [1][2]. The SPMC as shown in Figure 1 consists of four bi-directional switches that interface with their input and output terminals [3][4][5][6][7][8][9][10][11]. In order to fulfil the design of high performance and high-speed switching applications, IGBTs or MOSFETs have been employed.…”

This paper presents the new generation of advanced gate driver circuit based on IR2110 device for a Single-Phase Matrix Converter (SPMC) circuit topology that uses MOSFETs or IGBTs switches. The new generation of gate drive circuit uses less number of components, since a single IR2110 device can drive two power switches, thus reduce power losses and minimize the complexity of conventional circuit. An additional isolation of the upper and lower sides of IR2110 device features additional protection to the proposed gate drive system. As a result, the proposed gate drive circuit just uses four IR2110 gate drives in order to control eight switches of SPMC circuit, thus, solve the conventional bulky gate drive circuit problem in SPMCs operation. This is in line with the international power electronic technology road-maps to reduce losses, cost, volume, therefore to raise up the power density of power electronics converters. Validation have been done through the experimental test-rig. As a result, such new theoretical enhancements can be used as a novel foundation of future high power density of SPMC circuit topology and in-line with the Fourth Industrial Revolution (IR 4.0) which were characterized mainly by advances in technology
