Power unit introduction 1) Rectification bridge Its function is to rectify (turn AC into DC). There are two types of internal package of the rectifier bridge. There are 6 rectifier diodes inside the package, which are used in the three-phase input end of the power unit. There are two rectifier diodes inside the package, which are used in the three-phase input of the power unit and in the bypass circuit. The rectifier bridge voltage levels used are: 1400V, 1800V; 2) Thyristor Thyristor is used in the charging circuit and by-pass circuit to play a "switch" role. The thyristor voltage levels used are: 1400V, 1800V; 3) Electrolytic capacitor Its function is to filter the DC after the rectifier bridge is rectified. The voltage levels used are: 400V. The capacity used is 3300uF, 6800uF, 10000uF. 4) IGBT Its function is to invert (to change DC into AC). Most IGBTs are "dual-tube" (two sets of IGBT modules are encapsulated inside). The IGBT voltage levels used are: 1200V, 1700V; The IGBT current levels used are: 75A, 100A, 150A, 200A, 300A, 400A, etc

Power unit board 1. Unit power supply board Board function: Take power from the DC bus of the power unit and output 24V DC power for the unit control board. Board interface: Input interface: power unit positive and negative DC bus Output interface: 24VDC output, connected to the unit control board 2. Unit control panel The function of the board: 1) receive the signal of the main control system and provide the control signal to the drive board; 2) Conduct real-time fault monitoring and report fault information to the main control system; 3) Supply power to the unit drive board. Board interface: 1) Optical fiber interface for communication with the main control system; 2)24V power input interface: connected with the power board; 3) Driver signal (Top1, Top2, Lock interface: connected with the driver board; 4)15V power output interface: connected with the driver board to supply power to the driver board; 5) Overvoltage, undervoltage detection interface: connected with the positive and negative bus of the unit; 6) Lack of phase detection interface: fuse auxiliary switch; 7) overheating detection interface: connected to the temperature detection switch; 8) Power on thyristor drive signal interface: Connect the thyristor gate; 9) By-pass thyristor driver signal interface: connected to the by-pass thyristor gate; 10) Bypass OK signal detection interface: connected to bypass OK board. 3. Unit drive board Function of the board: receive the control signal of the unit control board, provide driving signal for the four-way IGBT on the unit, and monitor the drive fault and report it to the unit control board. Board interface: 1)15V power input interface: connected to the unit control board; 2) Input signal (Top1, Top2, /Lock) : connected to the unit control board; 3) Output signal (ERRout) : connected to the unit control board; 4) Output signal (TOP1, BOT1, TOP2, BOT2 IGBT driver signal) : connected to the C, G, E pole of TOP1, BOT1, TOP2, BOT2 IGBT respectively. 4. Bypass OK board Board function: After the unit control board sends out the side communication number, the by-pass loop is detected to detect the signal input to the unit control board. Board interface: Input interface: bypass thyristor A, K pole; Output interface: connected to the unit control board
