SIMULATOR OF CONDUCTION NOISE AND METHOD THEREOF

摘要

PURPOSE:To obtain a simulation waveform of a conduction noise in a short time coinciding precisely with a conduction noise flowing out actually from a switching power source. CONSTITUTION:This simulator has a memory which stores information for expressing an AC power source (1a) outputting a low frequency AC voltage, information for expressing a false power source circuit network with an observation circuit which can observe a signal waveform of a conduction noise flowing out to the side of the AC power source receiving the AC voltage from the AC power course, information for expressing a filter circuit which receives the AC voltage via the false power source circuit network to lower a high frequency noise passing and information for expressing a switching circuit which receives the AC voltage via the filter circuit to rectify and smooth the voltage and switches the voltage thus rectified and smoothed. The information for expressing the filter circuit is that expressing the filter circuit with an equivalent circuit of a normal mode.
