Explanation of Circuit Movement If the AC Input voltage(1) is confirmed to power device, this Input voltage is adjusted as DC wave form through EMI FILTER(2) and the first adjusting part(3). This adjusted wave form is input to PFC(4, Power Factor Correction) and makes the PFC circuit works and the output voltage(+390Vdc) by PFC circuit becomes a Main Input voltage of MAIN(5), STANBY(10) Switching part.
