Abstract

The load simulation converter（LSC） of the electronic load takes three-phase PWM converter（VSR） as basic structure and its current tracking performance

as the base of function achievement is related to the selection of inductance parameters.The relationship between current tracking performance of LSC and system parameters is established based on the mathematical model of VSR in complex space for the analysis of inductance limit at dynamic and steady state conditions.With the help of space vector

the influence of 3-phase switching state can be comprehensively considered and the performance of the system can be reflected.The proposed method can be used for the evaluation of LSC current tracking performance and the design of parameters.Finally

the correctness of the method is verified by simulation and experiment.
