  • SYSTEM FOR PROTECTION OF SOLID STATE ELECTRICAL DEVICES AGAINST OVER AND/OR UNDER VOLTAGE CONDITIONS
    Publication number: 20200077487
    Abstract: A system (100) for protection of solid state electrical devices against over and/or under voltage conditions, comprises an AC input (110), supplying an AC connected with fuse, AC filters (112), connected with the AC input (110) via the fuse, configured to filter the AC, rectifiers (114), connected with the AC filters (112), configured to convert the AC line voltage into DC line voltage thereby forming a DC bus voltage, buck converters (118), connected with the rectifiers (114), configured to step down the DC bus voltage thereby providing a first DC voltage, voltage dividers (116), connected with the rectifiers (114), configured to divide the DC bus voltage, thereby generating a second DC voltage, a threshold detector (120) connected with the buck converters (118) and the voltage dividers (116), a relay (122) connected with the threshold detector (120), the AC input (110) supplying the AC and one or more loads (124).
