AC 220 12V DC Power Supply



AC / DC converter is converting AC to DC. Its energy flow can be bi-directional. The energy flow comes from the energy source. The charge is called "rectification". The energy returned by the load to the power source is called the "active inverter".

The AC / DC converter input is 50/60 Hz AC. Because it needs to be rectified and filtered, a relatively large filter capacitor is essential. At the same time, it complies with safety standards (such as UI, CCE, etc.) and EMC Restrictions directive (such as IEC, FCC, CSA), the AC input side must add EMC speed wave power and use components that comply with safety standards, so that the size of the AC / DC power supply is limited.

Also, due to internal high frequency, high voltage and high current switching actions, it is more difficult to solve the EMCo problem, which is in the internal design of the high-density installation circuit. For the same reason, high-voltage, high-current switching causes a large increase in power loss, limiting high requirements. For the same reasons, high current and loss increase the loss of operation of many power supplies and limit the modularization of AC / DC converters.

Therefore, energy system optimization methods should be adopted to achieve three hundred

AC / DC converter can be divided into half-wave circuits and full-wave circuits according to the circuit connection mode, it can be divided into single-phase, three-phase and multiphasic according to the number of phases of the source. quadrants.
