Abstract
A novel three-phase constant voltage transformer for the triport UPS (uninterruptible power supply) system is presented. In this circuit, the unbalance of the loads and the asymmetry of input source voltages are compensated by the ring connection of the secondary windings of respective linear inductors. It is concluded that this principle can be applied to the conventional triport transformer with magnetic shunts
