Abstract
This paper proposes a kind of precision continuous adjustable voltage switch power supply which is based on single chip microcomputer control. The power uses constant frequency pulse width modulation technology which is based on the SG3525, through the control of single chip microcomputer, controllable gain amplifier realizes the continuous adjustment to output voltage. The output voltage circuit has a high precision and low consumption, etc, and can be adjusted continuously. The experimental re- sults show that the power can provide output voltage which can be changed from 1 kV-25 kV, and the maximum of output voltage error is 1.6%.关键词
