- Abstract
- Normally, various auxiliary loads are installed along with the main load in industrial
applications. Usually, load transformers are used to convey such types of auxiliary loads. The
transformers become energized when the loads are turned-on, consequently, high amplitude of inrush
current appears at the output of the uninterrupted power supply (UPS) system. To mitigate these high
current amplitudes, this manuscript suggests a three-phase line-interactive UPS system to counter the
inrush current during the turning-on of the auxiliary load transformer while powering the main load by
using a current controlled inverter. Experimental results of a laboratory-sized prototype are provided in
the support of the proposed UPS system for validation.
