Design and Analysis of a Novel Two-Switch Transformerless High Step-Up DC–DC Converter for Grid-Connected Renewable Energy Sources

IEEE Access
Renewable Energy Sources (RESs), particularly Photovoltaic (PV) systems, inherently produce variable DC voltages that often cannot meet load or grid requirements directly.

Common-Mode Resonance Damping and DC Voltage Balancing Strategy for LCCL-Filtered Three-Level Photovoltaic Grid-Tied Inverters

IEEE Access, 2020
The leakage current caused by common-mode (CM) voltage is a critical issue in transformerless three-level photovoltaic (PV) inverters, which can increase the output current distortion, bring extra power losses, aggravate the electromagnetic interference,

A Nine‐Level Common‐Ground Type Multi‐Level Inverter for Standalone and Grid‐Connected Applications

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
In this article a new multilevel inverter is designed and proposed by the authors. The inverter has used reduced number of switches and stress, and is suitable for grid‐connected applications. ABSTRACT This work proposes a new common ground (CG) 9‐level (9L) inverter with only nine switches and three capacitors.

Single-Phase to Three-Phase Unified Power Quality Conditioners Applied to Electrical Distribution Grids in Remote Areas

IEEE Open Journal of the Industrial Electronics Society
In remote areas, electrical distribution grids are typically single-phase due to infrastructure and cost limitations, which makes the direct supply of three-phase loads unfeasible.

Ripple‐Free Input Current Quadratic Converter Based on Watkin–Johnson Topology

IET Power Electronics, Volume 18, Issue 1, January/December 2025.
This article proposes a power electronics converter capable of providing high voltage gain while keeping a high‐quality input current ripple. The technique for achieving the zero input current ripple at a selected duty cycle consists of extracting two inductor currents from the source in a counter‐phase manner.
