The rapid development of the communication industry has greatly promoted the development of communication power supplies
.
High-frequency miniaturized switching power supply and its technology have become the mainstream of modern communication power supply systems
.
In the communication field
,
the rectifier is usually called the primary power supply
,
and the DC-DC
(
DC-DC
)
converter is called the secondary power supply
.
The function of the primary power supply is to transform a single-phase or three-phase AC power grid into a DC power supply with a nominal value of 48V
.
Currently in the primary power supply used in program-controlled switches
,
the traditional phase-controlled regulated power supply has been replaced by a high-frequency switching power supply
.
The high-frequency switching power supply
(
also known as a switching rectifier SMR
)
works through the high frequency of MOSFET or IGBT
,
and the switching frequency It is generally controlled within the range of 50-100kHz to achieve high efficiency and miniaturization
.
In recent years
,
the power capacity of switching rectifiers has continued to expand
,
and the capacity of a single unit has expanded from 48V/12.5A
, 48
V/20A to 48V/200A
, 48
V/400A
