摘要:
针对传统DC-DC变换器存在系统复杂、指令顺序执行、计算延时、效率低的问题,设计了一种以FPGA为核心的LLC谐振变换器。在对LLC谐振变换器工作原理分析、参数计算的基础上,充分利用FPGA并行运算快、实时性好的特点,解决了LLC变换器空载时打嗝问题;在中间添加信号调理电路利用稳压管和与门的作用解决了开关管误导通问题。最后,使用PSIM和QuartusⅡ软件进行了仿真和调试,结合样机实验,得出该变换器在全负载范围内实现了软开关,输出电压纹波小于±0.48%,效率达到 94.3%以上,符合设计要求。
Abstract:
In view of the problems existing on traditional DC-DC converters such as system complication, sequential execution of instructions, calculation delay, and low efficiency, an LLC resonant converter with FPGA as the core has been designed. Based on the working principle analysis and parameter calculation for the LLC resonant converter, the burp problem in no-load LLC converter is solved by making full use of the characteristics of fast parallel arithmetic and good real-time performance of FPGA;the false turn-on the switch tube is solved by adding a signal-adjustable circuit in the middle and making use of the function of the zener voltage regalator diode and the AND gate. Finally, PSIM and Quartus Ⅱ software are used to simulate and debug. Combined with the prototype experiment, it is concluded that the converter realizes the soft switching in the full load range, the output voltage ripple is less than ± 0.48%, and the efficiency reaches more than 94.3%, which meets the design requirements.
