摘　　要：在原型峰值电流控制DC/DCBoost型变换器的基础上,设计了一种对最小输入电流加以限制的新型峰值电流控制方式,给出了实现电路。计算机模拟与电路实验均表明,采用新型峰值电流控制方式且工作于混沌状态下的DC/DCBoost型变换器能够进一步降低电磁干扰(EMI)水平,具有实用价值。On the basis of general peak value current control DC/DC converter, the authors designed a new type of peak value current control DC/DC boost converter which can limite the minimum current, and given the experimental cir-cuit. Computer simulation and circuit experiment results demonstrated that novel peak value current control DC/DC con-verter operating at chaos has the better performance on depressing electromagnetic interference level than general peak value current control DC/DC converter.The new converter can be utilized practically.This work is supported by Outstanding Youth Science Fund of Henan Province (No.112001600).
