The Design and Realization of Intelligent Anticorrosive Power Based on the MCU

本文介绍了一种运用电力开关变换技术和高频开关技术并以单片机系统为控制核心的智能防腐电源。设计以VMOSFET作为功率开关器件,采用脉宽调制(PWM)技术。通过使用先进的传感器采样输出电压和输出电流,然后和给定的信号进行比较,经过A-D转换,由单片机结合改进的PID控制算法,产生连续的脉冲控制信号,调节输出电压的变化。

In this text,the intelligent anticorrosive power controlled by a single-chip computer is introduced,in which the converter technique or ETOP and the high frequency switching technique will be used.The buck half-bridge converter is made of VMOSFET and the theory of PWM is used.The signal of out-voltage and out-current i sampled by the advanced sensor is compared with the given signal and is transformed of A/D.The signal is operated by advanced control operation by a single-chip compute and a series of pulse are produced.So the out-voltage and the out-current can be regulated.
