Abstract

The invention discloses a surge protector with a simple structure, which comprises a resistance R1, a resistance R2, an electric capacitor, an inductor and a diode, wherein the negative pole of a diode and one end of the resistance R1 are connected to the two ends of the inductor respectively, the other end of the resistance R1 is connected onto the positive pole of the diode, the positive pole of the diode is grounded, the resistance R2 and the electric capacitor are in series connection, the other end of the electric capacitor is grounded, and the other end of the resistance R2 is connected between the resistance R1 and the inductor. The surge protector provided by the invention has the advantages that the circuit has a simple structure, can let out the surge in the moment of opening the power supply of the electric device completely, so as to avoid the damage of the inner circuit of the electric device caused by the surge.

Description

technical field [0001] The invention belongs to the field of anti-surge technology, and more specifically relates to an anti-surge protector with a simple structure. Background technique [0002] Since there are many electronic components integrated in the electronic equipment, the input surge current of the electrical equipment will have a strong impact and damage to the equipment when the power is turned on. It will connect the anti-surge circuit to the power port of the electrical equipment to protect the electronic equipment. . However, the existing anti-surge circuit has a relatively complicated circuit structure, and sometimes cannot fully discharge the input shock. Contents of the invention [0003] The invention provides an anti-surge protector with a simple structure, which has a simple circuit structure and can completely discharge the surge at the moment when the power supply of the electronic equipment is turned on, so as to avoid the damage caused by the surg...
