The invention discloses a control circuit for an electronic lock of an electric car charging gun, and relates to the technical field of electric car charging. The control circuit comprises a first PWM signal, a second PWM signal, a first front-stage driving module A, a second front-stage driving module A, a first back-stage driving module B and a second back-stage driving module B which are connected to a CPU; four switch tubes can be controlled and driven by only one driving power supply. The control circuit has a relatively small space volume because all elements are patches and the number of the elements is relatively small; the control circuit selects appropriate parameters through simple calculation, so that a power element of a field effect tube is in a safe working range in the normal working state.
