What kind of Marine boost power supply will be higher(2)

The quality of the resolution of the circuit schematic is usually done from a professional perspective. This power module can be divided into two kinds of bare board and packaged, according to an intuitive way of bare board, such as electronic components layout is reasonable and orderly, generous, orderly, and the net pad is lit upright. Also, stationary modules will not be able to see what's going on inside, but it's much better not to be exposed due to safety and performance levels. The soldering process can include both wave soldering and manual soldering, and the quality of the mechanized production process of wave soldering is superior to that of manual soldering.

high frequency switch
The rapid development of the communication industry has greatly promoted the development of communication power. High frequency miniaturized switching power supply and its technology have become the mainstream of modern communication power supply system. In the field of communication, the rectifier is usually called the primary power supply, and the direct current-direct current (DC/DC) converter is called the secondary power supply. The role of the primary power supply is to convert the single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V. In the primary power supply for program-controlled switches, the traditional phase-controlled regulated power supply has been replaced by a high-frequency switching power supply. Controlled in the 50-100kHz range for high efficiency and miniaturization. In recent years, the power capacity of switching rectifiers has been continuously expanded, and the single-unit capacity has been expanded from 48V/12.5A, 48V/20A to 48V/200A, 48V/400A.

Two: the components of the chip

The core problem of the Marine boost/buck voltage power supply is the IC, which is like the brain of the Marine boost/buck voltage power supply. The quality of the IC can directly affect the various working parameters of the Marine boost/buck voltage power supply.
