Current detection circuit

Disclosed in the utility model is a current detection module that is composed of a load module, a power supply module, a choking coil module, a current detection module and a control module. To be specific, the load module includes a switch unit. The choking coil module consists of a first coil and a second coil with the set number of turns; the second coil with the set number of turns is connected to a PCB board to form an induction coil by the second coil and the PCB board; the first coil that is connected between the switch unit and the power supply module generates an electromagnetic signal according to the current of the first coil; and the second coil generates an induced current according to the electromagnetic signal. The current detection module, which is connected with the second coil, obtains a detection signal according to the induced current. And the control module that is connected with the current detection module detects the current of the load module according to the detection signal. According to the utility model, the provided current detection circuit has the advantages of accurate detection, high reliability, low cost, and low spatial demand.
