Space Vector Modulation Method-Based Common Mode Voltage Reduction for Active Impedance-Source T-Type Inverter

IEEE Access, 2022
In recent years, many pulse width modulation techniques have been explored for three-level impedance-source inverters. Among them, a space vector modulation (SVM) technique using upper/lower shoot-through (UST/LST) insertion provides high voltage gain ...

Modulation Techniques for a Modified Three-Phase Quasi-Switched Boost Inverter With Common-Mode Voltage Reduction

IEEE Access, 2020
In a single-stage buck-boost quasi-switched boost inverter (qSBI), the shoot-through state insertion causes high amplitude common-mode voltage. Consequently, the qSBI becomes less attractive in transformerless photovoltaic (PV) systems.

Switched capacitor based cascaded half-bridge multilevel inverter with voltage boosting feature [PDF]

, 2021
Cascaded multilevel inverter (CMI) topology is prevalent in many applications. However, the CMI requires many switches and isolated dc sources, which is the main drawback of this type of inverter.
