Abstract

Disclosed is a circuit for converting a temperature change amount into a voltage change amount in a motor drive system, including a positive temperature change rate voltage generation module, a circuit bias module, and a temperature detection module that are integrated on a same substrate. An external power supply voltage is processed by the positive temperature change rate voltage generation module and the circuit bias module, and then inputted to the temperature detection module. The temperature detection module detects in real time the temperature change amount in the motor drive system, convert the temperature change amount into the voltage change amount, and transfer the voltage change amount to the circuit bias module, to allow the circuit bias module to output the voltage change amount. In this way, the conversion from the temperature change amount into the voltage change amount is realized.
