| Abstract: | This paper presents a practical method in analyzing the dissipation system of the inverter.After analyzing the experimental data of the headsink temperature of two dissipation systems cooled by compelling wind,this paper confirms the time constant of the headsink temperature on condition that the headsink is a matter of equality,and brings forward a practical method on calculating the headsink temperature.After comparing the experiment result with the calculating result,the paper reaches the conclusion that the designing method is reasonable and practical. |
