AC-DC converter is a device that turns AC power into DC, its power flow can be bidirectional, power flow from power supply to load is called rectification, and power flow from load back to power is called active inverter. AC-DC converter
AC-Alternatingcurrent is the meaning of communication, DC-Directcurrent is the meaning of DC, AC/DC transformation is to convert AC to DC, AC-DC converter is a device that turns AC power into DC, its power flow can be bidirectional, power flow from power to load is called rectification, and power flow is returned from the load to the power supply For active inverter AC/DC converter input of 50/60Hz, because of the need to rectify, filter, so the larger size of the filter capacitor is essential, at the same time because of safety standards (such as UL, CCEE, etc.) and EMC instructions (such as IEC, FCC, CSA), the AC input side is required to add EMC filtering and the use of safety. The standard components limit the miniaturization of the AC/DC power supply. In addition, because of the internal high frequency, high voltage and high current switching, the difficulty of solving the EMC EMC problem is more difficult, and the high density of the internal high density installation circuit is required. For the same reason, high voltage and high current switch. The consumption of power supply increases and the modularization process of AC-DC converter is limited, so it is necessary to optimize the design method of power system to achieve a certain degree of satisfaction. The AC-DC converter can be divided into half wave circuit and full wave circuit according to the wiring mode of the circuit. According to the number of power supply, it can be divided into single, three-phase and multiphase. It can be divided into quadrant, two quadrant, three quadrant and four quadrant according to the quadrant of circuit. POWER-ONE in the United States is the world's professional production of AC / DC power supply (AC/DC), DC / DC power (DC/DC) conversion products, its products are widely sold all over the world, and have been widely used and praised by the world industry. Especially in power plants, railways, aerospace and other departments, there are excellent qualities that other company products can not replace.
