Passive control of three-phase PWM rectifier and its damping characteristics of CSR

摘要

Due to the current mode pwm rectifier model has strong coupling and nonlinear characteristics, the traditional linear control theory can't achieve satisfactory effect based on passive control theory to realize current-mode PWM rectifier state variable linear resolve coupling, decoupling model. Based on the design of the direct current control strategy, the theory and simulation experiments prove the feasibility and the effectiveness of solutions and achieve the ideal control effect. Damping is studied through experiments of passive control of the effect on the stability of the current-mode PWM rectifier system. It provides a theoretical and technical support in the application of the high-power current type inverter.
