    1. Circuit description 1. 1 Power block 1.1.1 Outline The power block is compatible with the business electric power, 100 to 120VAC/220 to 240VAC (50/60Hz). The active filter circuit is adopted to suppress the higher harmonic current. The circuit block is composed of two switching regulators, the main power which is the configuration used the flyback converter system of pseudo resonance operation and the sub power which is the configuration used PWM (pulse wise modulation) system.

    1.1.3 Sub power circuit When the power switch is turned ON, the rectified and smoothed DC voltage (AC voltage x √2) is supplied to pin 5 of IC903, and is charged to C930 through pin 1. When pin 1 reaches 5.7V, oscillation is started in IC903, and the built-in output FET is put into operation to add the pulse voltage between pin 5 and pin 3 on the primary side of T902.
