AC Inlet & AC Input Filter
Capacitor (C )
AC Input Filter :
Reducing and filtering Noise from AC line.
Bridge Rectifier & Filter
Bridge Diode
Convert AC voltage into DC voltage by
rectifying and smoothing AC.
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
Rectifier and Output Filter
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
