Chopping and doubly-fed adjusting speed technique of doubly-fed machine based on 8XC196MC single-chip-computer

In this paper, a chopping and doubly-fed adjusting speed control strategy is pro-posed based on the adjusting speed principle of the doubly-fed machine. The circuit topology structure of a multi-functional converter, which integrates rectifier, chopper and inverter, is put forward. The control algorithm of chopping and doubly-fed adjusting speed based on the Intel 8XC196MC single-chip-computer is derived. The output initialization method of SPWM inverter and operation mode switching and control technique of the doubly-fed machine are studied. An experimental chopping and doubly-fed adjustable speed system of the wound rotor indue tion machine has been built. The experimental results show that the proposed scheme is feasible and practicable, and can also be used for doubly-fed brushless machine.
