Abstract—Intelligent Universal Intelligent Universal Transformer (IUT) is a multifunctional transformer accounts as an Intelligent Electronic Devices for the tomorrows Advanced Distribution Automation (ADA). IUT is a HV power electronic base transformer with full monitoring and control ability is introduced instead of traditional current transformer. HV oil free transformer utilization in IUT results in size and weight reduction, oil pollution elimination and maintenance free equipment. PI current source controller senses the input current of IUT and holds it in phase with input voltage to prevent harmonic distortion. In output stage, PI voltage source controllers regulate the output voltages result in favourable desired outputs and improve the performances under load and source disturbances. Automatic sag correction, DC voltage option, real time voltage regulation, reliable diverse power as 400Hz service, three-phase power from a single phase line, Harmonic Filtering, Flicker mitigation, options for energy storage and dynamic system monitoring are the resulting benefits of proposed control fashion and three layers IUT model.
