Abstract

This paper presents simulation and analysis of twelve pulse rectifier transformer unit configured in series and also in parallel to have higher current capability and reduced harmonics, which creates the current imbalance and hence circulating current can be observed with parallel connection. Balanced current can be achieved with the introduction of Inter Phase Transformer (IPT) while paralleling two six pulse rectifier in rectifier transformer unit. PSCAD is used for performing all the simulations.
