| Abstract |
This paper describes the steady-state simulation results of the three-level VIENNA I three-phase rectifier under distorted mains (230V / 400V @ 50 Hz) voltages. The rectifier is designed to operate at 50 kW rated output power. The total harmonic mains voltage distortion is 8.6%. The operation of teh rectifier is examined in case of L- and LCL-type AC-filters. The DC-link voltage is set at 650V. The applied constant switching frequency is 3.5kHz. Simulations are carried out with Simplorer (R). Component models are non-ideal. On the basis of teh simulation results, the line current THD and the losses of the active and passive components are determined. |
