Title:
RELAY DRIVING CIRCUIT AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/148632
Kind Code:
A1
Abstract:
Disclosed by the present application are a relay driving circuit and an air conditioner. The relay driving circuit comprises a control circuit, a power supply terminal, and a power supply regulating circuit. The power supply terminal and the relay coil form a power supply loop; the power supply regulating circuit is connected in series in the power supply loop, and the power supply regulating circuit is under control of the control circuit; after the relay is controlled to be closed for a preset duration, the control circuit controls the on/off of the power supply loop at a preset frequency and/or a preset duty cycle. Under the premise of ensuring the normal operation of the relay, the scheme effectively reduces the power consumption and heat generation of the relay, thereby improving the overall stability of the circuit in which the relay is located.
