Connect the input power supply to the primary winding of the transformer.
The input current flows through the primary winding, generating a magnetic field around the coil.
According to the principle of electromagnetic induction, the changing magnetic field induces a current in the secondary winding.
Since the secondary winding has fewer turns than the primary winding, the induced current in the secondary winding is larger than the primary current.
The induced current is usually alternating current (AC), which needs to be rectified into direct current (DC) to meet the load requirements.
By adjusting the parameters of the electronic control unit, the current in the coil can be controlled, thereby regulating the output current.
