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.

摘要： An amplifier comprised of a field effect transistor whose gate electrode is adapted to receive an input signal. An impedance converter couples the input signal to the gate electrode of the field effect transistor, the impedance converter being formed of n impedance converting stages, each stage having a relatively low output impedance.

This voltage limiting circuit includes m voltage-limiting elements, wherein n and m are integers (1, 2, 3, . . . ) and n is equal to or greater than m. In a preferred embodiment, the amplifier is formed of two field effect transistors connected in push-pull relation, each field effect transistor being provided with an impedance converter and a voltage-limiting circuit as described above.
