Method for implementing alternating current-direct current (AC-DC) general solid state power controller and controller

Abstract

The invention discloses a method for implementing an alternating current-direct current (AC-DC) general solid state power controller and the AC-DC general solid state power controller. Two direct current solid state power controllers are connected back to back in a reverse series mode; the power input end of one direct current solid state power controller serves as the power input end of the AC-DC general solid state power controller and is connected with a direct current power supply or an alternating current power supply, and the power output end of the direct current solid state power controller is connected with the power output end of the other direct current solid state power controller; and the power input end of the other direct current solid state power controller serves as the power output end of the AC-DC general solid state power controller and is connected to a direct current power supply reference ground or an alternating current power supply reference ground through a load. By the invention, the direct current solid state power controller and an alternating current solid state power controller can be generally used and interchanged, and research and development cost and maintenance cost can be lowered. The AC-DC general solid state power controller has a reverse blocking function, effectively suppresses magnetizing inrush current with an alternating current transformer load and is suitable for an alternating current power supply system with an optional frequency.

Description

technical field [0001] The invention belongs to the technical field of power electronics and electric engineering, and in particular relates to a method for realizing an AC-DC universal solid-state power controller and an AC-DC universal solid-state power controller. Background technique [0002] Solid State Power Controller (SSPC for short) is an intelligent power distribution device composed of semiconductor devices produced with the development of aircraft power distribution system, which can receive control signals from the host computer and report its status information; When an overload occurs, it will trip according to the anti-delay characteristic to protect the circuit and load equipment; when the load is short-circuited, it will quickly cut off the faulty load within tens of microseconds; the solid-state power controller has no arc, no contact, With the advantages of no noise, fast response, low electromagnetic interference, high reliability, and easy computer remo...
