This paper presents a matrix converter design for achieving maximum power density using a SiC device based on a front loading design. To design the matrix converter to achieve maximum power density, the conduction loss and the switching loss of the matrix converter are theoretically derived and validated by simulation and experiment. Based on these formulas, the relationship between the efficiency and power density are revealed by using a Pareto-front curve in order to solve the trade-off problem between the power density and the efficiency. Moreover, in order to promote the widespread use of the matrix converter instead of a BTB system, it is quantitatively evaluated that the power density in the matrix converter is increased by 4.19 kW/dm 3 in comparison to the BTB system. Moreover, the power density of the matrix converter that uses a SiC-MOSFET (ROHM) as the switching device with natural air cooling is 95.0% (2.1 kW/dm 3 ) of the calculated maximum power density. Thus, the power density of the matrix converter is improved by 57.5% by the maximum power density design method. Based on the results, the design method for a high power density AC-AC direct converter is established according to the requisite specifications.Index Terms-Front loading design, loss analysis, matrix converter, maximum power density design, Pareto-front curve

Output performances including voltage error and THD effected by hexagon vector and basic vector with traditional indirect space vector overmodulation method are analyzed, and an improved overmodulation method based on input current vector synthesized is presented. Simulation and experimental results are carried out to validate the effectiveness of the proposed method. Simulation results indicate that the proposed input current vector-synthesized overmodulation strategy has better output performances. The experimental results verify that theoretical analysis is right and the proposed method is feasible.

This paper discusses a maximum power density design for a matrix converter using SiC device based on front loading design. In order to design the matrix converter at maximum power density, the conduction loss and the switching loss of the matrix converter are derived theoretically. Based on these equations, the relationship between the efficiency and power density are discussed by Pareto-front curve in order to solve the tread-off problem between the power density and the efficiency. From the experimental results, the maximum efficiency is 98.3% with two phase modulation at 3.9-kW output power and 25-kHz switching frequency (Devices: SiC-MOSFET BSM00003A ROHM). Moreover, the maximum power density of the matrix converter reaches 2.12 kW/dm 3 (the design value is 2.22 kW/dm 3 ) with a natural air cooling. Thus, the design method of a high power density AC-AC converter using a matrix converter is established according to the specifications.
