        abstract = {Modern electronic systems require advanced power conversion technologies that offer high efficiency, compact design, and superior power quality. Power Factor Correction (PFC) circuits are essential in meeting these demands, optimizing energy transfer between AC and DC power systems. This research introduces an advanced totem- pole PFC topology that redefines traditional power conversion by eliminating complex diode bridge rectifiers, significantly reducing energy losses, and boosting system performance. Utilizing wide-bandgap semiconductor technologies like Silicon Carbide (SiC) and Gallium Nitride (GaN), the design achieves remarkable efficiency. It operates in boost mode during positive AC half-cycles and inverted boost mode during negative cycles, ensuring continuous, unidirectional energy transfer with minimal losses. This approach maintains near- unity power factor and lowers harmonic distortion. Experimental validation shows a power factor over 0.99, efficiency nearing 98%, and stable voltage regulation under various loads. A dual-loop control system, featuring voltage and current loops with a PI controller, adjusts PWM signals for precise current shaping and voltage stability. This technology has potential applications in areas like server power supplies, EV charging, renewable energy systems, high- performance computing, and industrial motor drives, showcasing the potential of totem-pole PFC in modern power electronics.},
