A Review of Modeling and Mitigation Techniques for Bearing Currents in Electrical Machines With Variable-Frequency Drives

open access: yesIEEE Access, 2022
The converter switching in variable-frequency drives can generate high frequency common mode voltage between the machine winding and the converter ground, leading to high frequency parasitic currents which can flow through the machine bearings unless ...

A New High Gain AC-Decoupled Transformerless Inverter for Photovoltaic Applications

open access: yesJournal of Applied Science and Engineering, 2022
Transformerless inverters are prominently used in the single-phase grid-connected system due to their reduced size, weight, and high efficiency. Common-mode leakage current is the main issue of transformerless inverters, which has to be mitigated.

Three‐phase transformerless photovoltaic inverter without common mode leakage current

open access: yesEngineering Reports, 2022
Since three‐phase transformerless (TPT) PV inverters have large common mode leakage current (CMLC), a TPT PV inverter without CMLC is proposed. The proposed inverter is derived from three single‐phase half‐bridge inverters and a boost converter.
