Abstract

The embodiment of the present invention discloses a positive and negative polarity conversion circuit and electronic equipment, wherein the positive and negative polarity conversion circuit is composed of discrete components. By adopting the present invention, it is possible to avoid damage to the electronic equipment caused by the user mistakenly connecting the positive and negative poles of the power supply. damage, protect the electronic equipment, and when the user mistakenly reverses the positive and negative poles of the power supply, the normal use of the electronic equipment can still be guaranteed.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a positive and negative polarity conversion circuit and electronic equipment. Background technique [0002] Electric energy is closely related to our life. The normal operation of electronic products, electronic instruments and other electronic equipment is inseparable from electric energy, and each electronic equipment has a great dependence on the voltage of the power supply. [0003] When connecting the power supply to the electronic equipment, the user needs to place the power supply according to the instructions, connect the positive pole of the power supply to the positive output port, and connect the negative pole of the power supply to the negative output port, but sometimes users mistakenly connect the positive and negative poles of the power supply in reverse , making the electronic equipment unusable, or even causing damage to the electronic equipment, affecting th...
