Abstract

This paper describes the main requirements and challenges regarding the application of a Matrix Converter (MC) for aerospace power conversion. The challenges are reviewed in terms of (i) the input-filter (and output-filter) design, (ii) the selection of semiconductor switches and commutation-strategy, and (iv) the PWM strategy. The aerospace application of the MC requires operation at an input-frequency of 360Hz to 800Hz. The required output-frequency is either 400Hz to operate as a power supply or variable frequency of a few Hz up to 1200 Hz for drive applications such as fans and air compressors. Operation at 800Hz input-frequency imposes restrictions on the selection of the input-filter component values. These restrictions require the MC to operate at a high switching-frequency. Consequently, the switches, commutation strategy, and PWM strategy should be selected properly to enable MC operation at the higher switching-frequency. This paper uses MOSFET switches and demonstrates suitable commutation and modulation-strategies that enable a MOSFET-based MC to properly operate at around a switching-frequency of 40kHz, single-sided or 20kHz, double-sided.

航空航天用矩阵变换器综述与实现

本文介绍了矩阵变换器(MC)在航天电源转换中的主要应用要求和面临的挑战。从(i)输入滤波器(和输出滤波器)设计，(ii)半导体开关和换相策略的选择以及(iv) PWM策略方面回顾了这些挑战。MC的航空应用要求在360Hz至800Hz的输入频率下运行。所需的输出频率是400Hz作为电源或变频器的几Hz高达1200hz的驱动应用，如风扇和空气压缩机。在800Hz输入频率下运行对输入滤波器分量值的选择施加了限制。这些限制要求MC在高开关频率下工作。因此，应该正确选择开关、换相策略和PWM策略，以使MC在更高的开关频率下工作。本文使用MOSFET开关，并演示了合适的换流和调制策略，使基于MOSFET的MC能够在40kHz左右的单面或20kHz的双面开关频率下正常工作。
