Abstract :
In order to solve the disadvantages caused by mechanical slide rheostat that they were big errors and low precision, a novel voltage regulation method for high voltage DC power supply was introduced. The key of this method were digital potentiometer Maxim 5455 and linear photoelectric coupling LOC110, and application programs were compiled using Visual Basic which was graphical compiling language, furthermore the communication between exterior and computer was carried out by ICP7044D module, in consequence the output value of high voltage DC power supply could be regulated with computer. The measured results showed that this method could accurately, conveniently and rapidly regulate the output value of high voltage DC power supply.
