长期以来,单晶片双向功率开关元件一直处于尚待开发状态,连同电流幅值的大幅度交变所引起的换流电路的困难和系统控制的复杂性,使矩阵式变流器的实验研究限制在很低的功率范围,低于1~3hp。这篇论文提出了一种新的3转1相模块式组合设计方法,和新的中到中高功率级的3合1集成双向半导体元件功率模块(IBPM)。这种组合电路分区优化的主电路集成模块设计可减少交-交变频器换流电路的寄生高频电感,使主电路接线终端数最小化,并简化交流总线的结构和配线设计。自适应时序换流的优化设计进一步提高了变流器在高幅度交流负荷下的可靠换流能力。论文给出了该变频器输入输出均获得高于几百Hz基频的满意的实验控制和结果及其双向控制能力,并验证了它的优化设计方法。
For a long time, the single-chip bidirectional power switching devices have been in the state of development, with the difficulty of commutation circuit caused by the drastic alternation of current amplitude and the complexity of system control, so that the experimental research of matrix converter is limited In the low power range, less than 1 ~ 3hp. This paper presents a new 3-to-1-phase modular design approach and a new 3-in-1 integrated bidirectional semiconductor device power module (IBPM) with medium to high power levels. The main circuit integrated module design of this combinatorial circuit partitioning optimization can reduce the parasitic high frequency inductance of the AC-DC converter commutation circuit, minimize the number of main circuit connection terminals and simplify the structure and wiring design of the AC bus. The optimized design of adaptive timing commutation further improves the converter’s reliable commutation capability under high amplitude AC load. The paper gives a satisfactory experimental control and result of the input and output of the inverter above several hundred hertz and its bidirectional control ability, and verifies its optimal design method.
