Title:
LOW-POWER CONSUMPTION MOTOR STARTER AND REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/102752
Kind Code:
A1
Abstract:
The present application provides a low-power consumption motor starter and a refrigeration device. The low-power consumption motor starter comprises a compressor motor loop (10), a compressor protective circuit (20), a voltage sampling circuit (30), and a processing circuit (40). The compressor protective circuit (20) is coupled to an input end of the compressor motor loop (10), wherein the compressor motor loop (10) comprises a compressor starting loop (110); the voltage sampling circuit (30) is coupled to two ends of the compressor protective circuit (20) and used for acquiring a voltage across the two ends of the compressor protective circuit (20); the processing circuit (40) is connected to the voltage sampling circuit (30) and used for outputting, when the voltage across the two ends of the compressor protective circuit (20) is less than a preset voltage threshold, a switching signal for turning off the compressor starting loop (110).
