Single-phase single-stage PV-Grid system using a five-level inverter has been investigated. Some of integration systems used two-stage converters, while others used single-stage converter. However, two-stage converters had a very complicated problem. The first converter acted as a maximum power point tracker to maximize power generated by sunlight energy to electric power, implemented by PV. Th...

In this paper, a hysteresis current control technique for a single-phase five-level inverter with cascaded H-bridge topology is proposed. The basic study to implement the logic for correct voltage-level selection, various schemes available in the literature have been described and will provide a useful framework and point of reference for the future development of hysteresis modulation for mult...

Electrified vehicles on the market today all use the classical two-level inverter as the propulsion inverter. This thesis analyse the potential of using a cascaded H-bridge multilevel inverter as the propulsion inverter. With a multilevel inverter, the battery is divided into several parts and the inverter can now create voltages in smaller voltage levels than the two-level inverter. This, amon...
