The mathematical and simulation model of three-phase voltage source rectifier (VSR) used in aircraft is introduced in this paper. Based on the model, the principle of the seven-segment space vector pulse-with modulation (SVPWM) control strategy is presented. The double closed-loop control method is applied in the PWM rectifier. The rectifier can realize unity power factor by adopting the fixed switching...
This paper presents a novel control method for PWM boost rectifier based on instantaneous power. Unlike most of the existing control strategies implemented in synchronous or p-q (active-reactive power) frame, the proposed method can provide unity power factor on the AC side in stationary frame. Rotating transformation and phase detection are eliminated, offering a very simple solution. Based on the...
The principles and technologies of var compensation implemented with static capacitors, static Var compensator and static Var generator are concisely presents. The simulation and study for these methods are made. These methods' merits and faults are also compared through the wave analysis after simulation. It is shown the SVG is even more advantageous to dynamically improve voltage regulation, stability,...
