A transformer performs many functions such as voltage transformation, isolation, and noise decoupling, and it is an indispensable component in electric power distribution systems. A distribution transformer has consisted of a configuration of iron or steel cores and copper/aluminum coils, with mineral oil serving as both coolant and dielectric medium. Inherent in this type of construction are regulation, significant weight, losses, environmental concerns, and power quality issues. A new kind of distribution transformer is proposed; one that can be made self-regulating, oil-free, and able to correct power quality problems. A power electronic transformer has been analyzed, simulated, prototyped, and tested. And this paper presents the result of above experiment.
