Abstract

The invention discloses a high-voltage isolated SCR and IGBT driver based on a wireless power supply technology. The driver comprises a primary power supply circuit (1) and a secondary power reception circuit (2), both the primary power supply circuit and the secondary power reception circuit are sealed, the primary power supply circuit is isolated from the secondary power reception circuit, and power is supplied to the driver in the wireless energy transmission manner between the primary power supply circuit and the secondary power reception circuit. The primary side is neither electrically nor physically connected with the secondary side, problems in insulation materials and assembling technology are avoided, contacts of the insulation material are prevented from being exposed, and the safety, sealing, flexibility, beauty and the like of the driver are higher, high-voltage isolated power supply is realized, and the inherent defects of the contact type energy transmission of a traditional driver are overcome.

Description

technical field [0001] The invention relates to the field of power electronic equipment, and a high-voltage isolated SCR and IGBT driver based on wireless power supply technology is mainly applied to the drive of power devices of high-voltage power electronic equipment. The wireless power supply of high-voltage isolation driver power supply for electronic equipment fundamentally solves the problem of high-voltage isolation that restricts the driver. Background technique [0002] With the continuous development of high-voltage and high-power power electronic equipment, the driver power supplies connected in series often need to withstand extremely high operating voltages. Recently, multi-level high-voltage isolation technology is more and more used in the driving system of the circuit to meet the needs of high isolation voltage, but it also makes the driver more and more complicated. At present, SCR and IGBT, as the mainstream power devices of power electronics, are developi...
