Abstract

The research work proposes a Gallium Nitride (GaN) based dual active bridge (DAB) converter for electric vehicle (EV) charging applications. The wide bandgap semiconductor device, GaN is implemented in the DAB topology of an Isolated Bidirectional DC-DC converter (IBDC). GaN-based DC-DC converters lead to higher efficiency, smaller size, faster charging, and reduced heat generation improving the overall performance of the EV charging system. The performance characteristics of GaN based DAB converter is analyzed both in simulation and hardware for EV charging application. The same analysis is extended to a Si based DAB converter and comparative results are presented. A 14.25 kW GaN based DAB and 10.5 kW Si based DAB is designed and evaluated using LTspice XVII software and a scaled-down prototype of 0.612 kW GaN based DAB and 0.25 kW Si based DAB is presented for experimental validation. Result analysis under similar operating conditions indicated an improvement of 36% more output power transfer on the GaN based DAB over the traditional Si based DAB. The developed prototype showcased improved levels of power, voltage, and current under same operating conditions. The power transmission in the developed DAB based IBDC topology is controlled using the single-phase-shift (SPS) control strategy.

Abstract

This study addresses the challenge of frequency stabilization in a complex two-area hybrid power system subjected to load disturbances. Area 1 comprises thermal, hydro, and wind power generation, while Area 2 integrates thermal, hydro, and gas turbine units, presenting a diverse and realistic system for control strategies. The inherent nonlinearities and varying dynamics of these generation sources, particularly wind power, necessitate a robust and advanced control solution. The proposed Puma optimizer-driven fractional-order proportional-integral-derivative (FOPID) controller is developed to enhance dynamic performance under load disturbances and renewable energy fluctuations. The proposed Puma optimizer-based fractional-order proportional-integral-derivative (PO-FOPID) controller is rigorously validated against a Puma optimizer-based proportional-integral-derivative (PO-PID) controller, a PSO-tuned PID controller, and a PSO-tuned fractional-order PID (PSO-FOPID) controller. The settling time and peak overshoot/undershoot are considered for comparison, while the integral of time multiplied by the absolute error (ITAE) performance index is used as the objective function to be minimized. The findings highlight the potential of combining Puma optimizer with fractional-order control for reliable frequency regulation in modern hybrid power systems.
