Those things about acdc power module and dcdc power module

dcdc power module: In the communication system, it is also called the secondary power supply. It is a DC input voltage provided by a primary power supply or a DC battery pack, and one or several DC voltages are obtained at the output terminal after DC/DC conversion.

acdc power supply module: This type of power supply is also called primary power supply. It obtains energy from the power grid and obtains a DC high voltage after high voltage rectification and filtering, for the DC/DC converter to obtain one or several stable DC voltages at the output end. The power is from a few watts. -There are products for several kilowatts, which are used in different occasions.

AC/DC power supply is a power converter whose input is AC and output is DC. For example, the power adapters of mobile phone chargers, notebooks, and tablet computers that we commonly use are all such power sources.

The power converter contains a step-down circuit, a rectifier filter circuit, and a voltage stabilizing circuit. In the application of dcdc power module, a wide input range is required, usually: 85V~265V AC input, high output power conversion efficiency, and can effectively improve energy saving efficiency. Full load efficiency is the best in AC/DC power supply design. A major consideration. Improving the efficiency of AC/DC converters and achieving better energy-saving performance is the advocacy of green energy.

Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. AC/DC is one type of switching power supply. AC/DC switching power supply-AC is alternating current, DC is direct current, it is rectified and filtered to obtain a direct current high voltage, for the DC/DC converter to obtain one or several stable direct current voltage at the output end, the power is from several watts Several kilowatts are available for different occasions. There are many specifications and models of this type of product, and the primary power supply (AC220 input, DC48V or 24V output) in the communication power supply according to the needs of users also belongs to this category.

The power converter contains a step-down circuit, a rectifier filter circuit, and a voltage stabilizing circuit. In dcdc power module conversion applications, a wide input range is required, usually: 85V~265V AC input, high output power conversion efficiency, and can effectively improve energy-saving efficiency. Full load efficiency is in the design of dcdc power module A major consideration.
