中频电源用单向电荷泵锁相环

Single-way Charge Pump PLL for Intermediate Frequency Power Supply

研制了一种适用于中频电源逆变控制电路的锁相环.该锁相环无环路滤波器结构,采用单向电荷泵直接控制压控振荡器的方法,在满足中频电源逆变控制电路对相差和抗干扰能力要求的前提下,大幅提高了频率捕获速度.

Developed a PLL apply to the invert control circuit of Intermediate frequency power supply. This PLL has no loop filter configuration, using single-way charge pump control VCO directly, not only meet the requirement of the phase offset and anti-jamming, but also greatly improve the speed of frequency capture.
