VHDA-AMSによる自己発熱対応DCDCの熱１Dモデリング手法

サーマルシャットダウン動作モデリングに関する問題と解決策

抄録

In recent years, further consideration on heat is required due to high performance and high density of electronic circuits. Switch mode power supply (SMPS) also required design including heat protection protection. In this paper, we confirmed the system in which the heat dissipation path from the switching element to the outside was constituted by the thermal resistance network by using VHDL-AMS corresponding to multi domain. Then, we show the problem of modeling and the solution which connects from the heating point to the thermal shutdown circuit by the thermal resistance network.
