Gallium Nitride (GaN) dc-dc converter feedback control field programmable gate array (FPGA) 27th International Conference on Electrical Machines and Systems, ICEMS2024, November 26-29, 2024, Fukuoka Institute of Technology, Fukuoka, Japan DC-DC converters are essential for providing a fixed voltage to power LEDs and automotive systems. This paper introduces the non-inverting buck-boost (NIBB) DC-DC converter, which uses GaN half bridges to achieve a 24V unity conversion ratio operation. NIBB converter has been developed and tested for high-frequency feedback control under simulated LED load conditions. The feedback control was employed using FPGA and a high-speed ADC. The converter performance is examined for the high-frequency feedback control at switching frequencies of 500kHz and 800kHz corresponding to changes in the load condition. In addition, the efficiency performance for two different PCB designs of NIBB power converter circuit boards are compared under different operating conditions.
