A new family of inverter topology for active neutral point clamped (ANPC) is proposed. The traditional ANPC gives the output voltage of half the input voltage which necessitates the use of higher input dc-link voltage. To fix this problem, a floating capacitor is used to increase the voltage of the output, which decreases the dc-link requirement. Moreover, no sensors are needed to stabilize the floating condenser for the proposed topology, which minimizes inverter complexities. The neutral point is connected directly to the load terminals, which decreases the leakage current and makes it suitable for solar PV integration. Two modes of operation of the proposed topology have been discussed while considering the voltage of the floating capacitor used in the topology. Furthermore, two extensions of the proposed topology with generalized structure have also been provided in the paper. A detailed comparison with similar topologies has been provided. The level-shifted pulse width modulation technique has been used for the control of the proposed active neutral point clamped topology. In order to illustrate the idea of the proposed active neutral point clamped inverter, the theory of operation and analysis is accompanied by simulation, and experimental waveforms obtained from a laboratory prototype are provided.
