Design of  the Capacitor Charge and Discharge System Based on the Microcontroller
Abstract: The article introduces a completely new device of high voltage charging and discharging, and has given a complete charging design device, which is based on three introduce electricity. By using the instantaneous discharging, it realizes high voltage releasing, people can get the needs of physic and chemistry process, such as explosion, impaction, shape changing and so on.
The device of high voltage uses SCR smart control model, place the flash microcontroller(AT89C2051)outside, arithmetic figure electric machine etc. Proceeding the assistant controls, from this charging the capacitor constant current. In this system is applies to the electric power and electronics technique, and applies to the information electronics technique. Controlling the electric power and electronics technique with the information electronics technique, the strong and week electricity gets well of application, it can say that the electronics technique has got the extensive application in this design.
This design of device of high voltage charging and discharging can charge electricity according to the customers’ different requests that is under the 1000V,the equipments is not have, moving conveniently, being used in industries and agriculture at any time. It is very popular in electronics profession, strong function in practical application, it solved the question that is inconvenient highly storage energy device in the past, and the function, the economic is further enhanced.
