Abstract:

The structure principle, circuit model and application of the super capacitor were introduced in tokamak experiment. The arc discharge power supply characteristics of high power ion source and the circuit topology of 1MW NBI arc supply for HL-2A tokomak are comprehensively analyzed. An arc discharge power supply circuit for 5MW NBI ion source has been developed by application of super capacitors, which can reduce the load of electric network and has smaller size, higher efficiency, simpler control and quicker response speed. A scheme for 5MW NBI ion source filament power supply using super capacitors supply and constant voltage control has been put forward, and the feasibility and technical advantages of the scheme have also been given. To equalize the voltages of individual super capacitor in energy storage by a numerous super capacitors in series and in parallel, this paper put forward a reliable and efficient voltage balancing circuit.
