摘要：This paper presentsan improved hysteresis current control method for five level T-type inverter.The proposed method is based on four hysteresis levels and performed togenerate switching signals of fundamental transistors in T-type inverter. Byusing generated signals through hysteresis controller, bidirectional switch inT-type inverter is triggered through the logical way. The system is detailed inanalytical expression and exhibited to generate five voltage levels at the outputof inverter. The improved technique is based on an error signal between theoutput current and the reference value. Therefore, the proposed modulationtechnique achieves the following output current at the desired value andensures high-efficiency conversion ratio at the output. In order to show thevalidity of the proposed method, the controller is compared with conventionalsinusoidal pulse width modulated T-type inverter. In performance results, it isobvious that the proposed method provides a lower total harmonic distortion incomparison with conventional method.
