Optimization of SiC-Based H5 and Conergy-NPC Transformerless PV Inverters
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2013The transformerless dc/ac inverters are critical components in the rapidly growing market of grid-connected photovoltaic (PV) applications. They are synthesized by combining available solutions in terms of the power-section topology, power-semiconductors manufacturing technology, and structure of the output filter. In addition, the silicon carbide (SiC)

NPC Multilevel Inverters Advanced Conversion Technology in APF
2018Multilevel inverters are most familiar with power converter applications. In this current paper, we discussed another possibility for DC/AC energy conversion. Converters based on current source inverters (CSI) configuration, take an important role in active power filtering in term of harmonics compensate and increasing system efficiency.

A Five-Level Boost NPC Inverter for Electric Vehicle
2020 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2020This paper proposes a five-level boost Neutral Point Clamped (NPC) inverter feeding an induction motor drive for an electric vehicle. Two partly rated isolated DC-DC converters are implemented to maintain the voltage at the DC-bus of the inverter constant irrespective of the variation in battery terminal voltage.
