摘要
一种用异或门及D触发器组成的0~±180°相位差测量电路,能够测量两个同频率的交流量的相位差及其相位关系。该电路可应用于并联逆变器恒反压时间的调频控制。
A kind of phase difference measure circuit which is composed exclusive or gate and D-flip-flop. The circuit can measure both phase difference and phase relation between two same frequency alternating-current quantity, the circuit is used for the frequency conversion and control of constant reverse voltage time of parallel inverter.
