In this paper a single-stage three-phase boost inverter with non-linear modulation is introduced. This inverter is capable of generating high-voltage AC output from a low-input dc source. In order to prevent voltage drop at the input floor, parallel paths of current are proposed in this converter and a new structure of boost inverter is applied. The performance of this inverter is generally based on charging inductors in parallel and their discharging in series. After analyzing the performance of the proposed converter, the dynamical equations governing the converter are extracted. This converter is simulated in MATLAB/Simulink and results check the validity of the equations. At the end, practical prototype is studied in laboratory and results are extracted, which evaluates the accuracy of the dynamic equations obtained in this new structure.
