1. A boost converter with a function of temperature adjustment, comprising:
a bridge rectifier, generating a rectified voltage according to a first input voltage and a second input voltage;
a first inductor, receiving the rectified voltage;
an absorption circuit, coupled in parallel with the first inductor, wherein the absorption circuit is selectively enabled or disabled according to a control voltage;
a power switch element, selectively coupling the first inductor to a ground voltage according to a PWM (Pulse Width Modulation) voltage;
an output stage circuit, coupled to the first inductor, and generating an output voltage;
a feedback compensation circuit, generating a feedback voltage according to the output voltage; and
a detection and control circuit, generating the PWM voltage according to the feedback voltage;
wherein the detection and control circuit generates the control voltage and adjusts a duty cycle of the PWM voltage according to a temperature-dependent voltage;
wherein the temperature-dependent voltage is related to a temperature of the first inductor.
