Comparison of Fuzzy Logic and PID Control in H‐Bridge Inverter: Performance Analysis and Response Optimization

Engineering Reports, Volume 8, Issue 2, February 2026.
Under identical conditions, we benchmark PID against Fuzzy‐Logic control for a single‐phase H‐bridge inverter. FLC achieves faster rise/settling with lower THD and better disturbance rejection than tuned PID while requiring explicit rule design—offering a reproducible baseline and deployment guidance for power‐quality‐constrained inverter applications.

Ultra High Step‐Up Soft Switching Converter Based on the Interleaved Structure

Energy Science &Engineering, Volume 14, Issue 1, Page 540-556, January 2026.
The proposed topology provides high voltage gain and enhanced efficiency at low duty cycles, thereby reducing conduction losses in the switches. Its interleaved structure ensures current sharing, while the switches experience both low voltage and low current stress, further decreasing conduction losses.

Oxide TFT‐Based Micro‐LED Pixel Circuit With Piecewise Linear Sweep Slope Signal for Improved Low Gray‐Level Expression

Journal of the Society for Information Display, Volume 34, Issue 1, Page 25-32, January 2026.
An oxide TFT‐based micro‐LED PWM pixel circuit employing a piecewise linear sweep signal is proposed. By separating low‐ and high‐gray emission phases, the circuit reduces the falling time by 70% and achieves accurate low‐gray‐level expression down to 41 G, enabling compact and stable operation for next‐generation micro‐LED displays.
