What kind of 48V input power supply will be higher(3)

The core problem of the 24V input power supply is the IC, which is like the brain of the 24V input power supply. The quality of the IC can directly affect the various working parameters of the 24V input power supply.

Three: Transformer components

Determine power, temperature and transformer. The transformer is responsible for the AC-DC 24V input power supply, and the energy overload will saturate.

48V input 24V input power supplyFour: Electrolytic and ceramic capacitors

The secondary power DC/DC converter of the communication power supply has been commercialized. The module adopts high-frequency PWM technology, the switching frequency is about 500kHz, and the power density is 5W~20W/in3. With the development of large-scale integrated circuits, the module power supply is required to be miniaturized, so it is necessary to continuously increase the switching frequency and adopt new circuit topologies. The power density of the module power supply has been greatly improved.

Electrolytic capacitors, aluminum electrolytic capacitors and monolithic gallbladders, which use sulfuric acid to make the insulating medium, large capacity can carry out smaller volumes for the above, and are marked with a + sign, some are marked with a mark, generally do low cross-linking and side-by-side Circuit filter with larger loss meson, integral aluminum electrolytic capacitor, due to the shortcomings of using special materials, the electrolytic performance is better than ordinary, the preferred frequency, but can not do too much capacity, it can be used to accurately circuits, such as oscillators, or timing circuits.
