    Chapter 6 Operation of Power Supply (APS-M602) OUTLINE This power circuit APS-T60 is composed of 2 units as shown as below. (Fig.1) APS-T602 is composed of AC inlet and input line filters mainly. APS-T603 is composed of rectifier circuits, PFC circuit and DC/DC converter circuit mainly. The power circuit APS-T60 is supplied 100~240Vac and it supplies 5 power sources to load circuits.

  • Page 52: Operation Of Power Supply

    Chapter 6 OPERATION OF POWER SUPPLY 1. Transition from AC ON to Standby mode When the AC source is supplied to this power circuit, the voltage rectified by D101 and smoothed by C105 is supplied to VH pin of IC102 through R125. VCC pin voltage of IC102 rises by current supplied to VCC pin through VH pin.
  • Page 53 Chapter 6 OPERATION OF EACH SECTION 1. Input Line Filter The Input line filter circuit is made up of capacitors (e.g. C1, C2, C101) and inductor chokes (e.g. L1, L2, L101) on APS-T602 unit and a part of APS-T603 unit, This section protects the noise generated by the power supply circuit from leaking out to AC line and from entering of the external noise inside the power supply circuit.
  • Page 54 Chapter 6 3. DC/DC converter The main parts of this switching converter are transformer T201, switching MOSFET Q103, control IC IC102 and output diodes D201, D202 and D203. This converter is Fly Back type. This means that energy is transferred from the primary to secondary when MOSFET Q103 is off. The main output is 6V line and auxiliary output is 14V and 17V line.
