Abstract |
This paper describes the analysis and simulation (by means of SaberÆÊ simulator) of a threelevel
voltage source inverter (VSI) to be used into a Flywheel Energy Storage (FES) System. The inverter
drives a permanent magnet synchronous motor. A high speed (up to 30.000 rpm) and a very low THD
current motor are required. To achieve this high speed value, a high output frequency (up to 1000 Hz) is
necessary; a two-level conventional VSI would require an unacceptable switching frequency to comply
with current harmonic distortion requirements. By this reason, three-level inverter topology appears as a
good solution because it is capable of generating high frequency and low THD output currents with an
acceptable switching frequency (around 6 kHz.). Two different switching strategies for the three-level
VSI are analysed and compared in this paper: Space Vector Modulation (SVM) and Natural Sampling
Modulation. Developed simulations have shown that three-level topology can fulfil all the above
mentioned requirements. |
