RESUMO
This work deals with the design and implementation of the digital instantaneous averaged values control for output voltages of the three-phase inverter with Underlands snubber, using the Buck-Boost converter for regeneration of the snubbers energy. The qualitative and quantitative analysis of the inverter power structure, snubber and auxiliary converter, as well as the project for a set of presented specifications is presented. All needed block models for the design of the control are shown, as well as the project methodology of frequency response control. Results of simulation complement the work and prove the presented methodology. For experimental validation, its developed a three-phase inverter with snubber and auxiliary converter, with output power of 4.5kVA, switching frequency of 50kHz, and with capacity to operate with full power for output voltage from 127V up to 220V. Experimental results of the power circuits and control performance complement the study.
