چکیده
this paper presents the new topology of three phase on line uninterruptible power supply (ups) by employing t-source inverter (tsi) with maximum constant boost pulse width modulation (pwm) control and the results are compared with the conventional uninterruptible power supply (ups). the conventional ups consists of voltage source inverter (vsi) with step up transformer or dc-dc booster which decreases the efficiency and increases energy conversion cost. the proposed three phase ups with tsi has the voltage boost capability through shoot through zero state which is not present in the conventional vsi. this proposed ups increases the efficiency due to single stage conversion, reduces the harmonics, increases the voltage gain and reduces the voltage stress. the performance of the three phase on-line ups with tsi is simulated in matlab / simulink software and the results are compared with conventional ups. the simulation and the theoretical analysis are validated with experimental results.
