Abstract
This paper proposes the development of double conversion Uninterruptible Power Supply using 3-Level Converter/TNPC Inverter. The Rectifier of proposed system is operating not only 3-Level boost PFC but also battery discharger. The Inverter is converting DC voltage to AC voltage. And in terms of the efficiency, 3-Level TNPC inverter is improved compared to the origin 2-Level type. To verify the validity of proposed system, experiments were carried out.
