    5-3. Power Supply Circuit The power supply block of this circuit board consists of the following two switching regulators. 1. The power regulator for improving power factor in order to conform this system to the power supply harmonics regulation. 2. The power regulator for the main power supply that supplies the necessary voltages to the signal circuit, deflection circuit and high voltage circuit.
  • Page 55 2. Power regulator for the main power supply The circuit system of this power regulator is the separate-excitation type current-resonant converter called EX-Z power supply using MCZ3001. The main power supply block consists of the control IC: IC602, the main switching FET: Q615 and Q616, the converter transformer: T602, the rectifier diode in the secondary circuit and the smoothing capacitor.
