In this study, a mode transition scheme between a single phase half bridge 2-level voltage source converter (VSC) and a 3-level T-type VSC is proposed. The efficiency of 3-level T-type VSC can be increased by the mode transition scheme. The mode transition scheme select the efficient operation method between a 2-level and 3-level VSC. The 2-level VSC or 3-level VSC operation method are selected depending...
This paper proposed an easy, simple, and flexible control scheme for a three-phase grid-tie inverter system. A half-bridge single-phase grid-tie inverter was designed with a proportional-resonant control, an admittance compensator, and scalar control scheme. This single-phase control method was expanded in a three-phase grid-tie inverter system with duplicating three individual phases with 120° apart...
This paper propose a control algorithm for integrated inverter to maintain desired output voltage waveform when power quality disturbances occur. Most of the reasons of power quality events are instantaneous voltage sag and a momentary interruption. Such, electrical disturbance are the conquered goal in the automated industrial process as semiconductor sites. To solve this problem, a large facility...
