This paper discusses the performance of a 5-level ANPC inverter for PV system which is evaluated by using the optimize design method. In addition, the performance of a 5-level ANPC inverter is then compared with the conventional 2-level inverter, 3-level NPC inverter and 3-level T-type NPC inverter. From the comparison results, within the range of switching frequency from 1 kHz to 1 MHz, the 5-level ANPC inverter can achieve the highest efficiency, and the 3-level T-type NPC inverter can achieve the highest power density converter.
