Virtual Flux Based Direct Power Control on Vienna Rectifier

This paper proposes the virtual flux based direct power control for Vienna rectifier. No need for the input voltage sensors, the current regulation loop and PWM voltage modulation block along with the active and reactive power decoupling are some of the salient advantages of this method that make it suitable for controlling the conventional active rectifiers. However, due to the three-level nat...

Power Factor Improvement in a Three Phase Circuit by using Vienna Rectifier and Buck-Boost Converter

Power factor is the ratio of true power or watts to apparent power or volt amps. The rapid placement of power electronic system in residential, commercial and industrial sides has energized the longing of an improved power factor to reduce the loss and cost. Good power factor deducts the losses and costs and ensure the longevity of electrical mechanism at a greater extent. Continuous researches...

A Review of Control Schemes for Active Power Filters in Order to Power Quality Improvement

Power quality has become a very important issue recently due to the impact on electricity suppliers, equipment manufacturers and customers. Power quality is described as the variation of voltage, current and frequency in a power system. Voltage magnitude is one of the major factors that determine the quality of power. Indeed, custom power technology, the low-voltage counterpart of the more wide...
