一個(gè)SMPS(附圖),各位大蝦來分析一下它的原理!


Nominal value Min Max Unit Conditions
INPUT
static
Input voltage, high voltage type 200-240 207 264 V
Input voltage, low voltage type 100-120 90 132 V
Input current, high voltage type 0.65 A
Input current, low voltage type 1.3 A
Mains frequency, both types 50-60 47 63 Hz
Power consumption 75 84 W @full load, max value @ 75% efficiency

OUTPUT
static
Output voltage 10.5 10 11 V @full load
Output current at full load 6 A @full load
Electrical isolation to primary SELV
Output power at short circuit 30 W @short cut output. Adaptor should not be damaged.
dynamic
Ripple at full load 450 mVp-p @full load, 0.1uF/47uF output capacitance @ 20Mhz, 25°C, 230V
Total output regulation -5 +5 %
Load characteristics See paragraph B2
Output voltage during pulsed load 8V See paragraph B2
Turn-on delay 2 sec

GENERAL
Efficiency 75 % @nom. input voltage and full load
