| Abstract: | A four-quadrant variable frequency driving system based on dual DSPs for inductive motor is designed. The PWM rectifier based on voltage-oriented vector control strategy was combined with traditional inverter. Through controlling input current in real time, the input currenl is nearly sinusoidal and its phase was the same as the grid voltage, the bi-directional transfer of the energy is realized automatically, and then the four-quadrant operation of variable frequency driving system was realized. The system functions were implemented by adopting dual DSPs control scheme, the particular design method of hardware and software was given. The experimental results prove the correctness and feasibility of the system. |
