This paper presents and analyses a new dynamic adaptive space vector PWM algorithm for four-switch three-phase inverters (FSTPI) fed induction motor under DC-link voltage ripple. By using reasonable mathematical transform, Space Vector PWM technique for FSTPI under DC-link voltage imbalance or ripples has been proposed, which is based on the establishment of basic space vectors and modulation technique...
This paper presents a novel STATCOM configuration for voltage quality improvement in wind power generation systems. The proposed STATCOM is formed by cascading two 3-level inverters, `bulk inverter' and `conditioning inverter', through a coupling transformer. Both inverters are powered by dc-link capacitors and they are charged by a small amount of active power drawn from the grid. To minimize switching...
