Abstract

The invention relates to the technical field of power equipment, in particular to a high-voltage high-speed electronic switch circuit. The high-voltage high-speed electronic switch circuit comprises an inductor and at least three groups of serial thyristor circuits connected with one end of the inductor, wherein the other end of the inductor is used for connecting with a bus; each group of thyristor circuits can be connected with a main controller through a trigger circuit and independently comprises two inversely parallel thyristors; and each thyristor can be conducted under the control of the main controller and the trigger circuit. The invention also discloses power equipment. According to the high-voltage high-speed electronic switch circuit provided by the invention, the problem in the prior art that the bus is instantaneously subjected to power loss in a circuit switching process can be solved. In addition, since the high-voltage high-speed electronic switch circuit only needs tocontinue for hundreds of milliseconds for each-time power supply, the high-voltage high-speed electronic switch circuit has the advantages of high reliability, long service life and low cost.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a high-voltage high-speed electronic switch circuit and electric equipment including the high-voltage high-speed electronic switch circuit. Background technique [0002] Compared with the current conventional mechanical switches, electronic switches have the advantage of fast switching speed, so they are very suitable for some specific occasions. For example: A certain equipment or load has two power supply circuits, A and B. Among them, the A circuit is the normal power supply circuit, and the B circuit is the backup circuit. When the power supply of circuit A fails, in order to continuously supply power to the load, the switching device of circuit B is required to act quickly to put the circuit into use. Due to the slow switching speed of conventional mechanical switches (tens of milliseconds to hundreds of milliseconds), the load may lose power instantaneously whe...
