The authors have devised a novel PWM control scheme capable of controlling a designated order harmonic while other low harmonic components are eliminated, based on the conventional low harmonic component elimination PWM control scheme. And it experimentally proved that the harmonic voltage in power systems could be suppressed, by means of controlling a self-commutated rectifier as a shunt active filter...
According to the principle of space vector PWM, the paper establishes mathematical models for rectifier in ABC , alphabeta and dq coordinates. It also makes one equivalent structure for the rectifier and designs a high power factor rectifier and a voltage-current closed loop. The paper simulates and analyzes the entire system with Matlab.
Semiconductor switching devices produce significant harmonic voltages as they chop voltage waveform during the transition between conducting and cutoff stages. The diode bridge rectifiers are considered as a major contributor to the power system harmonics and the consequences are varying from components overheating to communication interference. The scope of this paper is the harmonic voltages at...
This paper proposes analysis continuous conduction mode of buck-boost converter using bridge rectifier control is introduced. Analysis and test the comparate between PWM control and bridge rectifier control. The duty ratios are obtained by bridge rectifier control ix at 0.3 A this paper had tested the duty cycle at 0.8 which is bridge rectifier must be used ix at 190 A for control the output voltage...
This paper presents a method of using selective harmonic elimination PWM (SHEPWM) as part of a control strategy for a multilevel rectifier. Such a power converter can be applied as part of a solid-state replacement for a distribution transformer. The paper discusses problems with DC link voltage balancing on the converter and how SHEPWM can be manipulated to solve these problems. The full DC link...
