3.2 circuit description

3.2.1 power circuit
POWER VOLTAGE (+5V,-30V,V

EE

,,VF1,VF2) REGULATOR CIRCUIT

      After passing through the switching regulator. There is a +24V DC power via JP1.
      This power supply circuit employs fly back converter type switching regulator system.
      At the initial condition, as the level of point “I” is 0V, PQ4 keeps OFF condition.
    When +24V begins to rise up after power ON, the level of point “H” rises up and PQ1 turns ON.
    And then the power is applied to primary side of pulse transformer (PT1).
    When the power is applied to primary side of the PT1 , the level of point
“I” (secondary side of the PT1 ) rises up, and if it is exceed the zenner voltage
  of PD11(+5V), PQ4 turns on and the level of point “H” becomes 0V.
    Therefore PQ1 is in OFF condition and supplement to primary input of PT1
  is cut off, with that the level of point “I” becomes initial condition again and PQ1 turns ON.
    Thus , switching the supplement of power to primary side of PT1,
  secondary 5V,-30V,VF1,Vf2) is stable.
    The +24V DC pass through u1(LM2575S-5.0 voltage regulator)become Vcc-c steady.
