Research on Reduction of Electro-Magnetic Interference (EMI) Level of Boost Converter by Chaos Control

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).
