Abstract
The working principle of a three-phase step-up/down AC/DC converter .which are based on three-phase voltage-type PWM AC/DC converter and C'uk DC/DC converter, was analyzed to overcome the disadvantages existing in the commonly used three-phase step-up/down AC/DC converters which can t directly output continuously adjustable DC voltage in a wide range. According to the principle of simple control,easy engineering implementation and low switching frequency. A new control strategy based on SVPWM was designed with the expansion of zero-vector for the converter. Meanwhile, the corresponding mathematical model and reasoning were also presented. And a digital PI controller was designed with variable parameters and proportional-integral separation. Simulation results and analysis verify the validity of the control strategy.关键词
