Power & Switch Unit PDU IGBT 600V 50A
Power & Switch Unit PDU IGBT 600V 50A
The Power Distributing Unit (PDU) works as Protection, Switch & Fuse for high voltages and high power output controls. The PDU consists of electronic switch (IGBT or Power-MOSFET), “last chance” fuse, current monitoring and a micro-controller to switch the output, and to acquire data such as current and voltage in real-time or on request (polling).

System integration: PDU Units
System integration: PDU Units
A PDU Power Distribution unit can be integrated in a pressure housing. In the example, 7 PDU channels are integrated with switches (IGBT high voltage or MOSFET low voltage). It is controlled via MODBUS RTU, e.g. with the CIM controller or the SmartBMS.
The module can contain various functions. Several batteries or battery modules are interconnected here. The power outputs are distributed to one or more outputs. Optionally, charge balancing takes place, i.e. the charging input is distributed to the batteries for balanced charging.
The individual BMS interfaces of the batteries or battery modules are linked and various data outputs are available. These can be made available exclusively to the higher-level system (AUV CPU or SEM), a diagnostic unit or the external charger. The CIM (Custom Interface Module) can be used flexibly for these tasks. There are several interface protocols such as serial RS-232, RS-485 NMEA-0183, MODBUS RTU or CAN / FT available. Of course, all interfaces are galvanic isolated and EMC protected.
CAN safety, Modbus TCP or SiiS L2 are planned.
The power outputs can be equipped with PDU (Power Distribution Unit) channels. This means that each output is individually switchable and individually protected. Currents, voltages and temperatures as well as short circuits are recorded. External short circuits or an interchanged connection are protected by optional fuses.
