The transformer rectifier circuit and the power supply circuit is composed of the transformer, the diode bridge type circuit and the capacitance. The transformer uses the conventional iron core transformer and it changes the 220V AC electricity of the public power grid into the 12V AC electricity, and this 12V AC electricity is rectified and filtered by the diode bridge type circuit and the capacitance C1. The rectifier signal is led by VC1. If you add the three ports voltage stabilizer CW7812 and the capacitances C3 and C4 in the circuit, the whole circuit will be the voltage stabilization power supply circuit. The point B supplies the +12V DC voltage.
