Article Preview

Direct drive wind power system need full-scale high power converter, such as flying capacitor multilevel converter. On the realization of high power electronic equipment, an important problem is that the working frequency of high power devices is too low to apply excellent modulated technique such as PWM. In large-power equipment, the switching frequency of power electronics devices is such low that good control performance can't be obtained with a single converter. In order to overcome this problem, Carrier phase-shifted SPWM technique (CPS-SPWM) has been researched. Reactive power compensation and harmonic reduction are two relevant research problems that exist in wind power system. With the advancement of modern power electronics technology in both circuits and devices, new and better solutions are being proposed and applied to solve these two problems. To compensate reactive power, a flying capacitor type multilevel inverters with a Carrier Phase-Shifted SPWM(CPS-SPWM) switching scheme is proposed. All this verified by simulation and experiment.
