Abstract
A controller for an electromagnetic valve includes a control circuit, a hysteresis circuit, and a driver circuit. An output end of the control circuit is configured to output a first wave signal of a first frequency. An input end of the hysteresis circuit is connected to the output end of the control circuit. The hysteresis circuit is configured to process the first wave signal to obtain a drive signal including a second wave signal of the first frequency and a third wave signal of a second frequency. An input end of the driver circuit is connected to an output end of the hysteresis circuit, and an output end of the driver circuit is connected to the electromagnetic valve. The driver circuit is configured to drive the electromagnetic valve to operate based on the drive signal.
