| Abstract: | In order to achieve the control of three-level PWM rectifier without line voltage sensors, the virtual line flux oriented vector control strategy without line voltage sensors is proposed based on the mathematical model of three-level PWM rectifier, and a novel virtual flux observer is given. The experiment is conducted in the dual three-level inverter system. The experimental results show the system can improve the power factor of rectifier and has good steady and dynamic characteristics. |
