摘　　要：针对机载雷达对开关电源频率可控的要求 ,提出了一种新的基于锁相环的同步控制电路 ,该电路可控开关频率严格地与系统的脉冲重复频率 (PRF)同步。试验和实际应用表明本电路设计合理 ,提高了机载雷达设备的性能。To meet the requirement of the controllable frequency of the switch powers used in airborne radar ,a new synchronized control circuit based on phase-locked-loop is illustrated , with which the switch frequency can be controlled to work synchronously with the PRF of the system.. The experiment and application show that the design is reasonable while the performance of the airborne radar can be improved.
