TESTER FOR SILICON CONTROLLED RECTIFIER AND GATE PULSE TRANSFORMER

摘要

PURPOSE: A test apparatus is provided to perform easily, reliably and exactly a test under the operating condition similar to an actual operating condition by flowing actually operating current into a silicon controlled rectifier and a gate pulse transformer(GPT) to perform an operating test. CONSTITUTION: A test apparatus includes a waveform generating unit(11) for generating one of a sine waveform, a rectangular waveform and a triangular waveform. An output control and amplifier(12) adjusts a voltage of a rectangular waveform to 0 - 25V and then amplifies the voltage using a low frequency amplifier. A gate pulse transformer(GPT)(13) transforms the signal from the output control and amplifier(12). A selecting unit(18) selects only an output of the amplifier(12) from the outputs of the GPT(13) to display it a display unit(21). The display unit(21) displays the output of the GPT(13).
