【摘要】 文章提出了一种基于现场可编程门阵列(FPGA)的功率变换的模糊型跨周调制模式(FPSM,Fuzzy Pulse Skip Modulation)的实现方法,并将其应用于单端反激式开关电源的功率变换系统。实验研究表明,FPSM除具有跨周调制(PSM)效率高、响应速度快、鲁棒性强等优点外,较之PSM,它还能有效地降低变换器的输出电压纹波,消除音频噪声的影响。更多还原

【Abstract】 A method for implementation of fuzzy pulse skip modulation(FPSM) in power converters based on filed programmable gate array(FPGA) is described.It was used in the power converter of a single-end flyback switching power supply.The experimental results show that FPSM not only has high efficiency,quick response and strong robust characteristics,but also decreases output voltage ripple and eliminates audible noise,efficiently.更多还原
