摘　　要：对振动器采用单管和桥式脉冲电源供电时的工作性能做了详细的分析、比较和实验。结果表明,振动器采用单管脉冲电源供电时,利用自身损耗放电,放电速度慢,工作周期长;采用桥式脉冲电源供电时,振动器向直流侧回馈电能,放电速度快,工作周期短。在振动器工作频率较低的场合可采用单管脉冲电源供电,而在工作频率较高或调频范围较宽的场合需采用桥式脉冲电源供电。The working performances of vibrator using single IGBT and bridge pulse power supply are analyzed.The simulation and experimental results show that vibrator discharges using own losses, and its discharge speed is low and work period is long when supplys by single IGBT pulse power supply.When supplys by bridge pulse power supply, vibrator feeds back energy to direct current side ,its discharge speed is fast and work period is short.Therefore single IGBT pulse power supply is suitable for vibrator operating on low frequency and bridge pulse power supply is suitable for vibrator operating on higher frequency.
