Impulse voltage generator is a basic testing is a power supply device that simulates impulse overvoltage equipment of high-voltage laboratory, which such as lightning and operating overvoltage. The 1.2/50 μs standard lightning impulse voltage wave is simulated by using voltage double rectifier circuit, the basic impulse voltage generator circuit, driving circuit, microcontroller module circuit and so on. The main principle of this design is the use of single-chip control capacitor charge and discharge principle to simulate the production of 1.2 / 50 μs impulse voltage wave. The comparison between the software simulation and hardware test results verifies the rehabihty of the design.
