| With the fast developing technology of green energy, an ever-enhanced attention has been focused on the PWM rectifier in the field of power electronics applications. PWM rectifier might become an ideal electric appliance or a linkage between grid-line, characterized of pollution free and adjustable power factor. The PWM rectifier is classified as voltage-source and current-source according its topology. With the fast development of high power technology and the application of current-source rectifier in Superconducting Magnetic Energy Storage and the excellent protective performance of CSR, CSR becomes one of the hot spots currently. With this regards, the dissertation includes the following: First, the article analyzes the diferient topologys of CSR, the control method of SPWM, SVPWM and multi-rectifier are proposed. Second, the models of CSR are simulated by PSIM and the control system is made up of DSP (TMS320LF2407A) and CPLD (XC95108). Finally, a PWM-control CSR device is designed, The hardware and software about the design is particularly introduced in this article. |
