The common ground configuration in the proposed topologies effectively eliminates leakage current, making them ideal for grid-connected photovoltaic applications. The first proposed inverter topology consists of a single DC source, six power switches, two diodes, two capacitors, and one charging inductor.
A single DC-source, capacitor-based, five-level inverter is developed with double-boosting capability. To generate five-level AC voltage, it uses only seven semiconductor switches, two DC-link capacitors, and three diodes. The switches are operated efficiently through switching signals generated using a simpler low-frequency modulation scheme.
A current controller has been designed to deliver active power to the grid. A comparative analysis has validated the durability and feasibility of the proposed five-level inverters by comparing them with existing five-level inverters.
The proposed topology belongs to the family of multilevel inverters, known for their capability of generating stepped output voltage waveforms with considerably less harmonic content of the voltage and with higher voltage capabilities as compared to conventional two-level inverters.
