Part of the use of PWM rectifier voltage and current double closed-loop vector control strategies; inverter part of the introduction of rotor flux-oriented vector control method. Established a control system model, and its principle-depth analysis. This article first discusses the inverter and the inverters basic working principle and the corresponding vector control theory, and then mine hoist and then combined with a pay settlement has been reversible Frequency specific requirements, respectively, on the three-phase PWM rectifier and inverter for main circuit parameters and select Components. Finally, DSP (TMS320LF2407) as the core, the design of system hardware and software, completed a three-phase VSR digital contr
