Title:
CONTROL METHOD FOR RELAY, CONTROL CIRCUIT, AND PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2018/188025
Kind Code:
A1
Abstract:
A control method for a relay, a control circuit, and a processor. The control method comprises: obtaining a work state switching time for switching the work state of a relay and a power supply signal (810); determining, according to the work state switching time and the power supply signal, a delay time for controlling the relay to switch the work state (820); and controlling, according to the work state switching time, the delay time, and the power supply signal, the relay to complete switching of the work state at a power supply zero hour (830), the sum of the work state switching time and the delay time is a positive integral multiple of a half cycle of the power supply signal. On the basis of a control mode of the processor, a semiconductor switch and a delay line are not required, the required hardware cost is reduced, and the reliability is high.
