| 摘 要： | 提出一种新的AC／DC变换控制方法，系统以89C752为主体构成控制电路，与4046锁相环构成同步电路，输出控制GTR基本触发脉冲，该脉冲采用PWM控制方式产生，89C752的AD通道采样，它可以使在AC／DC变换时，从电网输入的电流近似正弦波，为功率因数为1，本控制系统可用于功率达kW级整流电源系统的控制。

| Abstract: | This paper provided a new method to control the AC/DC transform. This system cousists of 89C752 primarily with 4046 PLL, its output controled the GTR basic toggle impulse which is produced by PWM me-(thod.) The AD channel of 89C752 is used for sampling, it makes the current from power net approximate to sinusoidal wave, power factor is 1. This system is suitable for the control of rectifier power system, which power achieved kW grade. |
