摘　　要：高压模块电源为航空高压直流供电系统进行可靠供电。针对高压模块电源高效高功率密度的发展趋势,结合GaN器件导通电阻和寄生电容小的特点,基于移相全桥软开关+同步整流主电路拓扑,采用UCD3k系列数字电源控制器分段式PIDa反馈补偿控制方式,研制一款270 V输入、1kW/28 V输出的半砖模块电源样机。样机开关频率达500 kHz,功率密度达340 W/in^(3),最高效率达95.7%,实验验证了设计方案的正确性和可行性。The high-voltage module power supply provides reliable power supply for the aviation high-voltage DC power supply system.Aiming at the development trend of high-voltage module power supply with high efficiency and high power density,combining the characteristics of GaN devices with small on-resistance and parasitic capacitance,based on phase-shifted full-bridge soft switching and synchronous rectification main circuit topology,using UCD3138 digital power controller segmented PIDa feedback compensation control method,a 270 V input,1 kW/28 V output half-brick module power supply prototype is developed.The prototype has a switching frequency of 500 kHz,a power density of340 W/in^(3),and a maximum efficiency of 95.7%.The experiment verifies the correctness and feasibility of the designed scheme.
