摘要：

This paper studies electromagnetic interference noise source modeling with voltage source for electromagnetic compatibility design of synchronous DC-DC buck converter. The transient response of switching node voltage contains surge and ringing oscillation which can be attained by solving differential equation of power loop equivalent circuit model in the tested converter.
