Section 7 Circuit Description 7-1. G Board The power source of this unit is a power board consisting of an AC/DC block (an AC input filter circuit, a power-factor improvement regulator, and two types of insulating converters) and a DC/DC block (a DC input circuit, an input switching circuit, and DC-DC converters).

power IC, the switching FET is turned off. This time, a current decreasing at a gradient of (Vpfc-Vin (rms))/L flows through the rectifier diodes. When the current value becomes zero, the FET is turned on again. Current critical operation is realized by these operations. The PFC circuit controls these operations so that the envelope of the peak current flowing through the PFC choke becomes a current proportional to the sine half-wave waveform of an AC power voltage when viewed in the half-wave section of a commercial frequency.
7-1-2. DC/DC Block Power input of DC/DC block The 24 V (OUT_24V) generated from an AC power voltage by the insulating converter and 24 V (or 28 V) that is input from an external DC power circuit are input to the DC/DC block. The FET switch switching circuit controls FETs to prevent the two inputs from being supplied simultaneously to the G board.
