Abstract

A solid state relay for controlling a three-phase AC motor running direction is provided, a driver module, power components module, phase sequence detection module, phase lack detection module, and automatic phase correction and phase lack protection logic module. The input of the phase sequence detection module is connected to the three-phase power supply, and the output is connected to the automatic phase correction and phase lack protection logic module, to provide phase sequence detection and a phase sequence signal to the automatic phase correction and phase lack protection logic module. The input of the phase lack detection module is connected to the three-phase power supply, and the output is connected to the automatic phase correction and phase lack protection logic module, to detect a lack of phase and provide the lacking phase signal to the automatic phase correction and phase lack protection logic module.
