摘要： A transformer with an electrostatic shield body between its primary and secondary windings, one end of the shield body being connected to a zero potential point of the primary side from the AC standpoint. This reduces the capacity coupling between the primary and secondary windings. This transformer is particularly useful with an inverter.The transformer may include primary and secondary windings, each having a pair of terminals, and a magnetic core provided in connection with the primary and secondary windings magnetically. First and second static shield bodies may be provided at each side of the primary and secondary windings and therebetween, and these first and second static shield bodies are electrically connected to one terminal of the primary and secondary windings, respectively, so as to reduce the capacitance therebetween.

摘要： A transistor inverter includes at least a pair of switching transistors, a transformer with primary and secondary windings, a DC voltage source with a pair of output terminals and a voltage reference terminal, and a rectifying circuit connected to the secondary winding of the transformer. A collector electrode of one of the switching transistors is insulated from a chassis by an insulation means comprising a first insulating layer, a conductive layer such as a heat sink and a second insulating layer. The conductive layer is electrically connected to the voltage reference terminal of the DC voltage source so as not to produce an undesirable radiation through the chassis.

摘要： A surge current protection circuit includes an input terminal supplied with a rectified alternating voltage, an output terminal to be connected to a load, and a semiconductor controlled rectifier having its anode and cathode electrodes connected in series between the input and output terminals. The collector and emitter electrodes of a control transistor are connected between the gate and cathode electrodes of the rectifier. The base-emitter voltage is supplied with any sharp transients, and the transistor becomes conductive before the rectifier if the transients are sharp enough and of high enough amplitude. Conduction of the transistor prevents the semiconductor controlled rectifier from conducting surge currents and protects circuits connected in series with the rectifier.
