Abstract

For active neutral point clamped (ANPC) inverter, loss estimation model of power devices is built based on the principle of switching loss distribution, and an online adjustable loss distribution method is proposed to minimize the loss difference between every power device, by means of reasonably allocating different switching devices to undertake the switching loss and regulating the starting time and duration time of each mode. The method is deduced in detail and extended to the cases of variable power factor angles, which shows simple implementation and good effectiveness. Moreover, when the terminal voltage is clamped to neutral point, two zero-level clamped loop conducting (TZCC) is utilized for freewheeling through the reconstruction of the driving signals, therefore, conduction loss is decreased and the efficiency is further improved. Compared with the traditional single objective of loss equalization or efficiency optimization, the proposed method can achieve them both, so as to give full play to the advantages of ANPC inverters. Finally, the effectiveness of the proposed strategy is verified by simulation and experiments.

Key words： Active neutral point clamped (ANPC) inverter loss equalization driving signals reconstruction efficiency improvement
