    • An inverter unit for driving a motor with multi-phased currents, each of the phases being derived from a.c. input voltages that are applied to respective input terminals, rectified and smoothed by capacitors before being applied to parallel-connected switching elements to develop each of the phased a.c. outputs. The capacitors may be connected in series and/or in parallel together with the switching elements. In order to reduce the effect of the distributed inductance contributed by the conductors used to connect the capacitances and switches, and thus the need for large snubber capacitances to compensate for the distributed inductances, the connectors are given a geometry and an orientation that causes the inductances to be minimized. Specifically, the conductors are of a bus-plate form, having a large area for improving heat dissipation, and an orientation so that the magnitude and direction of currents flowing through the bus-plates tend to minimize the effect of the distributed inductances. The bus-plates may comprise one or more separate conductive plates and may be shaped to provide slots for viewing indicators on the capacitors.
    • 一种用于驱动具有多相电流的电动机的逆变器单元,每相都是从交流电源获得的。 施加到各个输入端子的输入电压,在施加到并联的开关元件之前由电容器整流和平滑,以开发每个相位的直流。 输出。 电容器可以与开关元件一起串联和/或并联连接。 为了减少由用于连接电容和开关的导体所产生的分布电感的影响,因此需要大的缓冲电容来补偿分布式电感,连接器被赋予几何形状和导向电感的方向 要最小化。 具体来说,导体是总线板形式,具有用于改善散热的大面积以及取向,使得流过母线的电流的大小和方向倾向于使分布式电感的影响最小化。 总线板可以包括一个或多个单独的导电板,并且可以成形为提供用于观察电容器上的指示器的槽。
