Abstract
A power supply circuit includes: a first power supply module and a second power supply module. An output end of the first power supply module is connected to a first output end of the second power supply module, and is configured to be connected to a first input end of the driving module. An output end of the first power supply module is configured to output a first voltage signal, and a first output end of the second power supply module is configured to output a second voltage signal. A second output end of the second power supply module is configured to be connected to a second input end of the driving module, so as to output a third voltage signal. The voltage signals are used to instruct the driving module to generate a gate turn-on signal.
