Design of type-2 fuzzy controlled unity power factor Vienna rectifier for electrical applications

Generally, a certain amount of energy is naturally lost during the transmission of useable electricity to the consumer. Specifically, the reactive power produced by the consumer’s electrical equipment, circulates in the power grid. In addition, electromagnetic interference that the consumer emits, also contributes to large losses in the electricity distribution system. Therefore, to overcome these issues the Vienna rectifier is proposed. To maintain the constant DC link with reduced power losses, the Type-2 Fuzzy Logic Controller (FLC) is introduced. The 3 ϕ diode rectifier is deployed to reduce the ripples contents from the circuit. With assistance of Adaptive hysteresis controller, a near unity power factor operation is achieved in this suggested work. The obtained outcomes are verified using MATLAB simulation platform.
