Control circuit used for circuit breaker, and electronic device

A control circuit used for a circuit breaker, wherein the control circuit comprises:

• a first coil,
• a second coil,
• a switch module, and
• an adjustable current supply module, the switch module comprises a first end, a second end, a third end, and a fourth end, and the adjustable current supply module comprises a first end, a second end, and a third end;
• the first end of the switch module is coupled to one end of the first coil, the other end of the first coil is coupled to the first end of the adjustable current supply module, the second end of the adjustable current supply module is coupled to the second end of the switch module, the third end of the switch module is coupled to one end of the second coil and the third end of the adjustable current supply module, and the other end of the second coil is coupled to the fourth end of the switch module;
• the switch module is configured to control a direction of a first current, wherein the first current flows through the first coil and the second coil;
• and
• the adjustable current supply module is configured to change a magnitude of the first current, wherein the first current is used to excite the first coil to generate a first magnetic field and excite the second coil to generate a second magnetic field, and the first magnetic field interacts with the second magnetic field, to control closing or opening of the circuit breaker.
