Abstract

The invention, which belong s to the power supply field, especially relates to a power supply circuit and a power supply apparatus. The power supply circuit including a rectifier filter module, an over-temperature protection module and a voltage conversion module is used; the over-temperature protection module compares an external temperature value with a preset temperature value and outputs a direct current or maintains a cut-off state according to the comparison result; and the voltage conversion module carries out voltage conversion when the over-temperature protection module outputs the direct current. According to the circuit, the over-temperature protection function of the power supply circuit is realized; and the advantage that the highest work temperature value can be set is realized.

Description

technical field [0001] The invention belongs to the field of power supply, in particular to a power circuit and a power device. Background technique [0002] When the power circuit is not working properly or the temperature of the external environment increases, the temperature of the circuit components will rise. Excessive temperature may burn the circuit components and even cause a fire. Therefore, an over-temperature protection function is generally added to an existing power supply circuit. However, the existing power supply circuits generally use the built-in over-temperature protection system inside the analog chip to realize the over-temperature protection function, and it is impossible to set the maximum operating temperature value according to the specific use environment. [0003] Therefore, the existing power supply circuit has the problem that the maximum operating temperature value cannot be set. Contents of the invention [0004] The purpose of the present ...
