Abstract: The new pulsed power equipment put forward higher performance requirements for the DC bus voltage. In order to reduce the impact of pulse load on the DC voltage fluctuation rate, the topology and mathematical model of three-phase rectifier with pulse load are established in this paper. Based on the existing passivity based control (PBC), an algorithm, virtual energy storage injection PBC (VESI-PBC), is proposed, in which the convergence rate of energy function is improved and the system stability is ensured. As the energy storage matrix is introduced into VESI-PBC, the stability and dynamic performance of the system are under discussion while increasing the value of virtual inductance L_n. In order to balance the performance requirements of the DC side and ensure system stability, the selection of L_n is correlated with the load pulsed frequency f_PL, and an adaptive selection function f (f_PL)is proposed in this paper as well. Finally, the simulation and practical experiments are carried out to verify the effectiveness of the VESI-PBC algorithm in reducing the fluctuation rate of DC bus voltage. It's also indicated that the algorithm is to control the active current to respond in advance to the dynamic changes and trends of DC voltage, which makes the system have stronger resistance to load disturbances. The algorithm is suitable for situations with high power levels and strong dynamic characteristics of pulse loads.
