12W ac to dc power supply Series K-042

The ac to dc power supply generally needs to be stepped down, rectified, filtered and stabilized to obtain the DC power supply as the power frequency DC power supply. The rectifier circuit converts power frequency alternating current into pulsating direct current. The filter circuit filters out the AC components in the pulsating DC, reduces the AC components and increases the DC components. The voltage regulator circuit adopts negative feedback technology to further stabilize the rectified DC voltage. The method of ac to dc power supply is divided into three categories according to the type of DC power supply, namely half-wave rectifier circuit, full-wave rectifier circuit and single-phase bridge rectifier circuit.

When electronic components are working, they will need to use a DC power supply for power supply. But due to higher battery costs, we generally just use devices with lower power consumption. In order to change this situation, ac to dc power supply appeared.
The ac to dc power supply generally needs to go through step-down, rectification, filtering and voltage regulation, and the obtained DC power supply is a power frequency DC power supply. The rectifier circuit converts power frequency alternating current into pulsating direct current. The filter circuit filters out the AC components in the pulsating DC, reduces the AC components and increases the DC components. The voltage regulator circuit adopts negative feedback technology to further stabilize the rectified DC voltage.
The method of ac to dc power supply is divided into three categories according to the type of DC power supply, namely half-wave rectifier circuit, full-wave rectifier circuit and single-phase bridge rectifier circuit.
