Abstract :
A new improved SMES chopper circuit is proposed for improving the energy storage and discharge efficiencies. The results obtained verify that the improved SMES circuit has longer energy storage time and lower control demand for the whole SMES system, and further results in longer energy discharge time with higher discharge efficiency.
