power typically about 30% nominal generator power. Therefore, the losses in the power electronic converter can be reduced, compared to a system where the converter has to handle the entire power, and the system cost is lower due to the partially-rated power electronics. This chapter will introduce the basic features and normal operation of DFIG
How Capacitors Work. I like to answer the question of "How does a capacitor work?" by saying that a capacitor works like a tiny rechargeable battery with very low capacity. But a capacitor is usually charged and discharged in a fraction of a second. So it''s not used for the same purpose as a battery.
