Abstract

A power supply device (100), including choke coils (CID1, CID2), voltage and current measurers (120a, 120b), a temperature sensor (130) and an operational circuit (140), wherein the voltage and current measurers (120a, 120b) are used for measuring a current (I1) flowing through the choke coils (CID1, CID2) and a voltage (V1) on a changeover switch; the temperature sensor (130) is used for measuring an initial temperature (T[0]) in an initial state; the operational circuit (140) is coupled to the voltage and current measurers (120a, 120b) and the temperature sensor (130); and the operational circuit (140) is used for: executing a power model (142), so as to calculate a first transient power (TP[1]) of the choke coils (CID1, CID2) on the basis of the initial temperature (T[0]), the voltage (V1) and the current (I1); and executing a thermal model (144), so as to calculate a first transient ideal temperature (TTI[1]) of the choke coils (CID1, CID2) on the basis of the first transient power (TP[1]). The present disclosure further relates to a temperature measurement method for the power supply device (100), and an electrical system (ES1, ES2).
