Previous studies have primarily focused on the magnetic coupling behavior between the main and auxiliary winding under symmetrical bipolar operation conditions. However, practical power electronic systems often operate under combined ac-excitation and superimposed dc-bias currents applied to the main winding. To addres...

The transition to decentralized renewable energy requires advanced Battery Energy Storage Systems (BESS) with precise management. While Cascaded H-Bridge (CHB) converters offer flexibility for power flow and State of Charge (SoC) balancing, high cell-level complexity hinder their adoption. This paper proposes a hardwar...

This paper investigates voltage regulated balanced sinusoidal grid current control under unbalanced and distorted grid conditions, where double-frequency power and harmonic oscillations. To avoid instability, delay, and computational complexity associated with PLL-based synchronization, a PLL-less Grid Voltage Modulate...

Gallium Nitride (GaN) transistors offer many advantages for power electronics converters, such as compact size and high-frequency operation. However, accurate loss estimation and calculation of the various losses in these transistors are generally more complicated compared to other power semiconductors due to the devic...
