Abstract

A power supply apparatus (100), comprising a bus bar (BUS1), a circuit measurer (120), a temperature sensor (130) and an operation circuit (140). The bus bar (BUS1) is coupled to an inverter (110) and a motor (MOT1). The temperature sensor (130) is configured to measure an initial temperature in an initial state. The circuit measurer (120) is configured to measure a voltage (V1), a current (I1) and an alternating current frequency (F1) on the bus bar (BUS1). The operation circuit (140) is coupled to the circuit measurer (120) and the temperature sensor (130). The operation circuit (140) is configured to solve a resistance value signal (R1) on the basis of the alternating current frequency (F1), solve a first transient power of the bus bar (BUS 1) on the basis of the current (I1) and the resistance value signal (R1) on the bus bar (BUS1), solve a first temperature rise value of the bus bar (BUS1) on the basis of the first transient power; and add the initial temperature to the first temperature rise value so as to obtain a first transient ideal temperature of the bus bar (BUS 1). The present invention further relates to a temperature measurement method (400) for the bus bar (BUS1).
