Aging circuit arrangement for switch triode

An aging circuit arrangement for switch triode comprises a pulse generator, a pulse power amplifier and an aging plate in sequential connection; a input DC source is respectively connected with the pulse power amplifier and the aging plate, and connected with the pulse generator by a voltage stabilization circuit. The utility model composes a pulse power amplifier by connecting a switch triode to a three-terminal voltage-stabilizer, and enables the amplitude of the output pulse signal of the three-terminal voltage-stabilizer continuously adjustable in a large range by a potentiometer, thereby, improves using flexibility, and is suitable for the aging of various switch triodes. The utility model also has the advantages of simple line, less components, small volume and low power consumption.
