摘　　要：针对传统升压变换器升压能力不足的问题,提出一种改进型磁集成高增益Zeta变换器。分析了该变换器的工作原理以及工作模态,推导了输出电压增益公式,分析了二极管、开关管、电容的电压应力,引入磁集成技术对电感进行耦合,减小了变换器体积和电感电流纹波。与传统Zeta变换器相比,电压增益提高了(3D+1)/D倍,电感电流纹波减小1/2。通过PSIM仿真软件对理论分析进行仿真验证,并制作实验样机对仿真和理论分析进行了验证。An improved magnetic integrated high-gain Zeta converter is proposed to solve the problem of insufficient boost capability of the traditional boost converter.The working principle and working modes of this converter are analyzed,the formula for output voltage gain is derived,and the voltage stress of diode,switching tube and capacitor are analyzed.The magnetic integration technology is introduced to couple the inductor,which reduces the volume and inductor current ripple of the converter.Compared with the traditional Zeta converter,the voltage gain of the proposed converter is improved by(3D+1)/D times while its inductor current ripple is reduced by half.The simulation software PSIM was used to perform simulations,and a test prototype was fabricated to verify the simulations and theoretical analysis.
