Abstract

The invention discloses a surge protection-type DC voltage conversion system. The surge protection-type DC voltage conversion system is characterized by mainly comprising an amplifier P2, an RS trigger U, an amplifier P3, an NOT gate A1, a capacitor C3 and the like, wherein a forward end of the NOT gate A1 is connected with a Q pin of the RS trigger U and a reverse end is connected with a positive electrode of the amplifier P3; and the positive electrode of the capacitor C3 is connected with a negative electrode of the amplifier P3 and the negative electrode passes through an inductor L and then is connected with an S pin of the RS trigger U. According to the surge protection-type DC voltage conversion system, voltage limiting can be carried out on input voltage; and instantaneous high voltage can be suppressed within a safe voltage range value when appearing in the input voltage, so that the surge protection-type DC voltage conversion system is prevented from being damaged by the instantaneous high voltage.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a surge protection DC voltage conversion system.
