DC-DC power module is very widely used in today's society, and some electrical appliances used in daily life are also applied to it. Do you understand the importance and structure of DC-DC power module? Today, Xiaobian will take you to understand.

The importance of DC-DC power module:

DC-DC power module is a compact, high quality regulated power supply products, using advanced manufacturing technology. Because the module power supply is simple to use, it has the advantages of convenient expansion and good maintainability when composing the system. Therefore, it is widely used in aerospace, communication power supply, automotive electronics, electronic equipment, power control and other fields. These module power supplies usually require a wide operating power range (36 V to 75 V) and high output power (can provide all-brick module power up to 700W), and the power density is very high, cooling design is a big problem.

For example, the half brick output power of 200W module power supply, its conversion efficiency is 89%, then 24.7W of electrical energy into heat, if there is no cooling measures, half brick module power supply may be damaged due to overheating. Therefore, in the design of high-power module power supply, appropriate heat dissipation design is more and more important.

Power structure of DC-DC power module:

The key components of the power structure of DC-DC power module are: pulse width modulator, optocoupler, VDMOS and Schottky diode.
