AC Inlet & AC Input Filter
Inductor
(L)
Capacitor (C )
AC Input Filter :
Reducing and filtering Noise from AC line.
Bridge Rectifier & Filter



Bridge Diode
Capacitor
Convert AC voltage into DC voltage by
rectifying and smoothing AC.
Converter
Reduce the high voltage to a lower voltage.
Power MOSFET , PWM IC Control : Control the high frequency
switching pulse width and frequency to stabilize the output.
SW Transformer : Step down the voltage with a high frequency
transformer.
Rectifier and Output Filter


Diode

Capacitor
Turning the AC into DC and filtering smoothing
the ripple of the rectified voltage
Feedback Circuit
Check error from secondary side and transfer
to primary side (Control circuit)
Optocoupler : Isolation and transfer signal from
secondary to primary.
 Error Amplifier : Control output voltage is
stability.
