Figure 4-11 Block Diagram of Power System
The power supply configuration of the system describes as following:

The power supply module can be divided into AC-DC power board, DC-DC power board,
battery and battery connecting board.

High-voltage programmable ARM and power management FPGA are on the DC-DC power
board.

Power output by the power supply module is transmitted to main board, and then it is
output to control panel, 4D drive board and the display by the main board.

Battery is connected to the DC-DC board via the battery connecting board and connecting
cable of BTB sequentially.
