Title:
RELAY DRIVING CIRCUIT AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/148633
Kind Code:
A1
Abstract:
Disclosed in the present application are a relay driving circuit and an air conditioner; the relay driving circuit comprises a first driving power source, a second driving power source, a switch circuit, and a control circuit; the switch circuit is connected in series between the first driving power source and a coil of the relay; the control circuit is used to control the switch circuit to be disconnected after the relay is started for a preset period of time. In the solution, when the relay is powered on, the coil of the relay is driven by using the first driving power source so as to ensure that the relay starts normally and quickly; after the relay is finished starting, the relay coil is driven by using the second driving power source; thus, the power consumption and heat generation of the relay are reduced while ensuring the normal operation of the relay, thereby improving the overall stability of the circuit in which the relay is located.
