Abstract

Auxiliary resonant transform pole inverter (ARCP) has the advantages of high efficiency and low loss in high frequency and high power field. However, in practical application, the problem of neutral point voltage deviation will lead to the increase of failure rate of ARCP soft switch. In this paper, a neutral point voltage active disturbance rejection control strategy was proposed to solve the problem of neutral point voltage deviation of ARCP bus divider capacitor and the failure of zero voltage opening of main switch tube caused by neutral point voltage deviation. The influence of bus capacitor equivalent series resistance (ESR) on neutral point voltage and AC side voltage was analyzed, and a neutral point voltage model including bus capacitor ESR in variable sequential control mode was established. On this basis, the neutral point voltage active disturbance rejection controller was designed and the auxiliary tube was used to control the overcharge regulation time, which realize the current balance of the three-phase auxiliary branch resonant inductor, achieving the goal of neutral point voltage stability, zero voltage opening of the main switching tube and improving the efficiency of the inverter. Compared with 97.0% inverter efficiency in PI control mode, active disturbance rejection control mode can achieve 97.5% inverter efficiency at maximum power. The control strategy is easy to implement as it doesn’t need to change the circuit structure. The effectiveness of the proposed control strategy was verified by simulation and experimental results.

Key words： auxiliary resonant commutated pole inverter; active disturbance rejection control; neutral point voltage; soft switching
