(9) Power circuit block diagram

Block diagram

The power circuit is composed of the main section, the high voltage circuit, the FW signal section, and the heater lamp drive circuit.
The main section directly rectifies the AC power current and switch-converts with the DC/DC convertor, and rectifies again and
smoothes to form each DC power.
In the high voltage circuit section, the 24V output of the main section is switch-converted by the DC/DC convertor and rectified and
smoothed to form the high voltage output.
The FW signal section fullwave-rectifies the AC power to supply signal output at the timing of 0V.
