4-in-1 PDU (DC-DC & Inverter & pre-charge board & CCU)

All-in-one:are mainly used in electric buses, commercial vehicles, BCS.It can be used as a DC power supply converter and provides 0-380V AC power for the power supply of compressors, with high integration (DCDC/DCAC/CCU/PTC), etc
Mass-produced model::2-in-1 PDU, 2-in-1 drive, 4-in-1；

Brief descriptions of the functions of each component:

1. CCU (Central Control Unit) Control Module: Usually serving as the main control unit of the system, it is responsible for the control logic, signal processing, and fault diagnosis of the entire system. It may contain a microprocessor or other control chips to achieve monitoring and control of the status of vehicle equipment.

2. DC-DC Module: A direct current-direct current converter. Its main function is to convert one DC voltage into another DC voltage. It is commonly used to convert the high voltage of the battery into the voltage required by the vehicle's low-voltage electrical appliances, or perform the opposite conversion.

3. DC-AC Module: A direct current-alternating current converter, also known as an inverter. Its function is to convert a DC power supply into an AC power supply for use by on-board AC equipment, such as air conditioner compressors (rotors), oil pumps, and air pumps.

4. PDU (Power Distribution Unit) Module: Responsible for power distribution and management in the high-voltage system. It provides functions such as charging and discharging control, power-on control of high-voltage components, overload and short-circuit protection of circuits, high-voltage sampling, and low-voltage control to protect and monitor the operation of the high-voltage system.
