This paper explicate the modeling and simulation of an alternate configuration to the conventionaltransformer based online Uninterruptible power supply(UPS). It proposes a transformerless three phase online UPS withpower factor correction. The proposed model consists of Battery bank, half-bridge rectifier, Auxiliary circuit , Split DC busand an inverter. Auxiliary circuit consists of switching leg(low rating) and an inductor , employed for charging the batterybank during normal operation of UPS and also to maintain the DC bus capacitors voltage during backup operation. Thisconfiguration adds the advantages by reduction of overall size, cost and weight of the system. The system is modeled andsimulated using MATLAB/SIMULINK. Detailed control design, circuit operation with the simulation results have beenpresented in paper for verification of its feasibility and behavior
