Abstract

In satellite electrical power supply systems, DC-DC power converter types at
different switching frequency and various power range have been used
extensively. It is must be reduce converter EMI on other devices. In this paper,
EMI spectrums at low power and high frequency switching converter for two
state, hard switching and soft switching, are compared together. In order to
increase the reliability of the converter, a new topology is proposed. Also, a new
method for reducing EMI noise spectrum has been used. This suggestion is
corroborated by simulation results.
