The embodiment of the invention provides a power supply control device, a guide circuit and a power supply control method of an alternating current charging pile, and belongs to the field of electric vehicle charging control. The power supply control device comprises a level conversion module used for outputting an invalid brake signal according to the voltage of a target detection point; the timer is used for outputting a first PWM (Pulse Width Modulation) signal and a second PWM signal which are complementary to each other in response to the invalid brake signal; the signal converter is used for converting the first PWM signal into a target PWM signal and outputting the target PWM signal to update the voltage signal at the target detection point; the microprocessor is used for triggering detection of a voltage signal at a target detection point when a low level signal in the second PWM signal is received; and under the condition that the amplitude of the voltage signal is detected to be a set value, the alternating current charging pile is controlled to start charging. The charging pile has the beneficial effects that the power consumption of the charging pile in the charging process is reduced, the response speed is higher, the circuit design is simplified, and the hardware cost is reduced.
