1) POWER INPUT : AC 100 ~ 240 V Input.
2) EMI NOISE FILTER CIRCUIT : Circuit to decrease noise to be flowed outside and to be generated in circuit.
This is consisted of high frequency filtering capacitors and choke filter.
3) AC-DC RECTIFIED CIRCUIT : Circuit to change AC Voltage to high DC Voltage.
This is consisted of Bridge Diode, Capacitor.
4) NOISE REMOVAL CIRCUIT : This is consisted of RC circuit, deleting Peak Noise.
5) MAIN TRANSFORMER : This change primary High Voltage to designed secondary low Voltage.
6) 15V / 5V RECTIFIED AND FILTER CIRCUIT
: This regulate DC Voltage to input at Transformer for stable secondary voltage.
7) SWITCHING PWM CONTROL : This transfer primary DC Voltage to main transformer after switching effectively.
8) FEEDBACK : This is circuit to use circuit control, circuit protection function.
9) INVERTER SWITCHING FET
: This transfer DC Voltage to input from Power Side to inverter transformer after Switching effectively.
10) INVERTER TRANSFORMER : This change DC Voltage to input from Inverter FET to AC Voltage.
11) INVERTER CONTROLLER : This is circuit to use inverter circuit control, circuit protection function.
