    Abstract

  • Abstract

    A Pockels Cell feedforward driving source based on DC modulation was proposed, which was applied to photon modulation. Aiming at the scattering effect of distribution parameters on wave propagation in circuit, an equivalent model circuit was built to simulate the pulse wave transmission in circuit and the influence of the scattering effect of distributed parameters on the triggered flow of the power switching device was analyzed. It was found that the scattering effect of distributed parameters on the switching drive signal resulted in a slower front edge of the drive pulse, which prolonged the triggered flow delay of the power switching device and increased the rising edge of the power pulse, thus increasing the delay time of pulse transmission. Some methods, including driving circuit improvement, circuit wiring optimization, and augment of an LC network matching circuit, were adopted to improve drive pulse transmission time delay. Experiment results indicate the pulse transmission delay of the improved circuit dropped remarkably from 300 ns to 100 ns in comparison with the original circuit.
