摘要： PROBLEM TO BE SOLVED: To realize a large multi-parallel capacity unit of a self-arc- extinguishing semiconductor switch element 10 effectively utilizing the capacitance of a single element 10 with a small economic load. SOLUTION: A unit, having filter capacitors 11U connected to both ends of one parallel/multi-parallel conversion modules (10UP, 10UN) is used as a basic unit. Such basic units are connected in multi-parallel with respective phases. The respective basic units are wired as follows. A large floating wiring impedance 13U, intrinsic to the basic units is interposed between the basic units and DC terminals 2PT/2NT. A small floating wiring impedance 14U is interposed between the capacitor 11U and the conversion module (10UP/10UN) in the basic unit. The large floating wiring impedance 13U to DC terminal 2PT/2NT is intrinsic to each basic unit and is operated to correct a current balance of the basic units. However, since the electromagnetic energy storage thereat is absorbed by the capacitor 11U at turning off, it is not the load on a current cut-off capability of the switch element 10U.

摘要： PROBLEM TO BE SOLVED: To miniaturize a serial multiplex inverter where a plurality of single-phase cell inverters are connected in series on an output side by providing a smoothing capacitor between a forward converter that converts AC into DC and an inverter that converts DC into AC. SOLUTION: The DC input current Idcu-Idcw of each single-phase inverter is calculated, and the current value is used to estimate variation ΔVdcu-ΔVdcw of the DC input voltage of each single-phase inverter for correcting output voltage command Vu * -Vw * of each phase of the inverter. The electric power supplied to a load from the smoothing capacitor by the single-phase inverter fluctuates by twice the AC output frequency. So, the input current and voltage of DC is easy to fluctuate much, and reducing the capacitance of the smoothing capacitor makes fluctuation of the DC voltage further large for easier occurrence of fluctuation in the torque of a dynamo electric motor. By estimating this without a DC voltage detecting means for effectively correcting a voltage command, the torque fluctuation is suppressed, resulting in a smaller power converter.

摘要翻译：要解决的问题：为了使多个单相电池逆变器在输出侧串联连接的串行多路反相器的小型化，通过在将AC转换为DC的正向变换器和转换为DC的逆变器之间设置平滑电容器 DC进入AC。
解决方案：计算每个单相逆变器的直流输入电流Idcu-Idcw，并且使用电流值来估计用于校正输出电压指令Vu的每个单相逆变器的直流输入电压的变化ΔVdcu-ΔVdcw 变频器各相的 * -Vw * 。由单相逆变器供给平滑电容器的负载的电力波动为交流输出频率的两倍。因此，DC的输入电流和电压容易波动很大，并且减小平滑电容器的电容使得直流电压的波动更大，从而更容易发生发电机的转矩的波动。通过在不使用用于有效地校正电压指令的直流电压检测装置的情况下进行估计，抑制了转矩波动，导致功率转换器的功率变小。版权所有（C）2004，JPO＆NCIPI
