Document Type and Number:
WIPO Patent Application WO/2017/076137
Kind Code:
A1
Abstract:
Disclosed is a power supply circuit. The power supply circuit comprises a battery, a relay, an external power connector, a step-up module, a step-down module, a first diode, and a second diode, wherein a normally open end of the relay is suspended, a normally closed end is connected to a positive electrode of the battery, a common end is connected to an input end of the step-up module, a first coil end is connected to a positive output end of the external power connector, and a second coil end is connected to a negative output end of the external power connector; the positive output end of the external power connector is connected to an anode of the first diode and an input end of the step-down module separately, a cathode of the first diode is connected to an output end of the step-up module to form a first voltage output end, and an output end of the step-down module is connected to a cathode of the second diode to form a second voltage output end; and an anode of the second diode is connected to the common end of the relay. Also disclosed is a gas stove. The present application implements dual power supply, thereby prolonging the service life of the battery.
