Abstract :
In order to filter out the common-mode and differential-mode interference of DC/DC converter output power, restrain the power´s ripple, reduce the transmitting interference of power, and increase the anti-interference ability and stability of power system, we analyze the internal structure of DC/DC converter, describe its working principle, and take mechanism analysis of the noise produced by it. According the result, I will bring forward the integrating nonlinear filter method as well as introduce the designation and calculation method of filter inductance. According to the experiments, the power of this system works stably and satisfies the output need of system´s power.
