본문

The active neutral-point-clamped (ANPC) inverter is a popular multilevel inverter for various industry applications. In a recent attempt,

an improved topology that integrates a flying capacitor to enhance the voltage gain from half to unity has been presented [11].

Retaining the benefit of unity-gain, this paper proposes a new ANPC topology with two improvements. Firstly, the voltage stress of

the flying capacitor is reduced by half. Secondly, the charging of the flying capacitor at 0 level is made possible to achieve uniform

charging over the power cycle. Comprehensive analysis is presented and experimental results of a prototype are presented for

validation. Finally, the extension of the topology with increased number of output voltage levels generation is briefly discussed.
