摘要： 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.
摘要翻译：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。

摘要： A control unit including an inverter (1) and a terminal block (2) connectable to wires (8) in which an external signal for the inverter (1) is directly delivered to the inside of the inverter (1) when a first additional device (3a) is not connected to the inverter (1), and an external signal for the inverter (1) is delivered via an internal circuit in a first additional device (3a) to the inside of the inverter (1) when the first additional device (3a) is connected to the inverter (1). The terminal block (5) includes screws (14) for connection to external signal wires (8) and upper and lower sets of contact pieces (15, 16) that can be pressed together or shorted when the inverter (1) is not connected to the first additional device (3a). The first additional device includes pins (4a) having separate upper and lower contact surfaces (51a, 51b) so that when the pins are received and clamped between the contact pieces (15, 16), the current path is diverted through the additional device and then back into the inverter. A substrate (33) having separate upper and lower contact surfaces (34a, 34b) can also be used. Further additional devices may be mounted in a sequential manner with current diversion into the additional devices. The inverter and additional devices also include aligned heat radiating pins (11a).

摘要： A circuit for providing an overcurrent protection for a power element, such as an IGBT, MOSFET or bipolar transistor, which is inserted between the power supply and a load, the protection circuit comprising a control circuit that provides an input to a gate amplifier at the power element gate. The gate amplifier comprises a photodiode that is connected between the amplifier power supply and the power element gate. The photodiode provides a clamp of the gate voltage in the event of an overcurrent and communicates optically with a phototransistor to provide a detection signal that can modify the control circuit operation. Specifically, the detection circuit can modify the input to the control circuit or control the output of the control circuit so that the energization of the power element is stopped or limited. The control can be through Darlington-connected transistors at the output of the phototransistor.
