| Abstract: | For developing the characteristics of composite switch,accurately evaluating the heating levels of electric and electronic units within composite switch,a vibration simulation model of switch is built to analyze low-voltage composite switch,and the temperature-lifting feature analysises of the bidirectional triode thyristors(triac) and of that after adding heat sink are carried out.By adding heat sink,the sinking heat of composite switch is decreased obviously.The simulation research should be very helpful in controlling composite switch,prolonging its period of validity,and developing large-scale integrated composite switch. |
