What are Step-up and Step-down Transformers? This is a very useful device, indeed. With it, we can easily multiply or divide voltage and current in AC circuits. Indeed, the transformer has made the long-distance transmission of electric power a practical reality, as AC voltage can be “s...
Transformers Transformer is a passive electrical device that converts voltage and current through electromagnetic induction. There are two types of transformer: the step-up transformer and step-down transformer. The underlying physics that govern the operation of transformers is the Faraday's Law ...
Transformers change the voltage of a power supply to meet the needs of individual consumers, specific appliances or subsystems within an appliance. As the names imply, a step-up transformer converts power to a higher voltage and a step-down transformer reduces voltage. A community power grid in...
Almost all piezoelectric transformers are used for step-up-type transformers and they are seldom used for step-down-type transformer. We have developed a novel step-down piezoelectric transformer utilizing the piezoelectric transversal effect. As this transformer can be driven with lower frequency than...
The authors present an analytical model for a voltage step-up/step-down DC/DC converter without transformers. The proposed topology is a combination of classic buck and boost converters in one single circuit but with differing operational principles. The converter is developed for a wind power ...
