This study presents a power factor correction-based single-ended primary inductance converter (PFC-SEPIC) feeding brushless DC (BLDC) motor drive for low-power household appliances. In a conventional scheme of BLDC motor, the speed is varied by controlling the duty ratio of high-frequency pulse width modulation signals, which increase the switching losses in the voltage source inverter (VSI) feeding...
Supplying power for DC energy storage unit of power quality compensator by rectifier will produce much harmonic and decrease power factor. Active power factor correction technology can resolve the problem, but it will bring much switching loss and put forward higher requirements to the frequency and stress of power device. It proposed soft switching power transformation technology to control switching...
This work presents compensation algorithm schemes used in power quality conditioners applied to three-phase four-wire systems, allowing harmonic current suppression and reactive power compensation which results in an effective power factor correction. The strategies used to extract the three-phase compensation currents are based on the synchronous reference frame method. Although this method is itself...
The paper proposes novel FACTS based stabilization scheme for maximum energy utilization of a tidal energy system using particle swarm optimization PSO search technique. PSO is implemented in the control of a hybrid low cost dynamic filter/capacitor compensation DFC and static VAR compensator SVC (TCR+FC) scheme. The dynamic self regulating control method uses real time error to stabilize the tidal...
Supply power for DC energy storage unit by rectifier circuit produced harmonic and decreased power factor. Active power factor correction (APFC) resolved these problems, but this kind of hard switching circuit produced much consumption. It proposed a strategy that using soft switching power transformation technology to control switching devices. An improved scheme based on zero voltage transition...
A single-phase three-level pulsewidth modulation (PWM) AC/DC converter with the function of power factor corrector and active power filter is proposed to reduce harmonic currents flowing into the power system and to draw a nearly sinusoidal current with unity power factor. The circuit topology of the adopted three-level PWM AC/DC converter is based on a conventional two-level full-bridge rectifier...
