摘　　要：针对无源功率因数补偿的不准确,设计了一款基于单片机的因数智能补偿装置,该装置能跟随负载功率因数变化确定不同的电路补偿参数以达到智能补偿节电的目的。装置硬件部分包括交流电压、电流、功率采集单元,单片机控制电路以及阵列式电容开关控制电路。试验表明该系统在不同感性负载情况下都能将功率因数提高到0.97,同时不会出现过补偿现象。Aiming at the inaccuracy of passive power factor compensation, a power factor intelligent compensation device based on MCU is designed. The device can determine different circuit compensation parameters according to the change of load power factor to achieve the purpose of intelligent compensation and electricity saving. The hardware part includes AC voltage, current, power acquisition unit, MCU control circuit and capacitors array switch control circuit. The experiments show that the power factor can be increased to 0.97 under different inductive loads, and no over-compensation will occur.
