摘要
应用单片机AT89S52和PWM调制器件SG3525,设计制作了一种直流脉冲电源,利用SG3525调节脉冲电压,利用AT89S52控制脉冲的频率和占空比,从而实现了输出脉冲的频率、电压和占空比的连续可调。实际应用表明,该脉冲电源具有调节范围宽、稳定性好、结构简单的优点。
A DC pulsed power supply was designed by use of the PWM adjustor of SG3525 and singlechip micro computer AT89S52, the SG3525 was used to adjust the pulse voltage, and the AT89S52 was used to control the pulse frequency and duty cycle. The way make the frequency, voltage and duty cycle of the pulse power supply to be adjustable conveniently and continuously. Practical application indicates that the power supply is wide regulating range, good stability and simple structure.
