摘要
在功率因数校正电路(APFC)基础上,巧妙利用单片机控制数字电位器实现了对电压反馈网络的调节,从而实现输出电压在一定范围内的自适应控制。此策略不仅可以降低对电网污染而且实现了输出电压的可控,可应用在母线电压调节以及输出功率控制等方面。
The adjustment of voltage feedback net by MCU controlling digital adjustable resistance on the base of APFC was realized, and also the auto control of output voltage was achieved. With this policy, the pollution of power net could not only be reduced, but also the auto control of output voltage be realized, which could be applied in the adjustment of voltage of generatrix, the auto control of output power, and etc..
