Page 39 Chpater 6 B) Reduce input harmonic current Normally switching power supply circuit is capacitor input type. Input current of this power supply has many harmonics, because of the conduction angle of input current is narrow. Therefore, an input current is distorted and this is a cause of low power factor. Main purpose of Power Factor Correction Control Circuit is reducing input harmonic current.
Page 40 Chpater 6 d) Over Voltage Limit Output voltage is detected by winding voltage of Bl-82 (T101).This voltage is same as Vcc of IC101 (pin6).If output voltage becomes over voltage condition, pin 8 of IC101 to be pulled up through zener diode ZD102,then power supply is shut down. e) Over Heat Protection Over heat protection is detected Soldering parts temperature of Ql,Q2(MC102) by TH102 and temperature of winding of T101 by thermo-fuse.
