Internal resistance of communication high voltage energy storage cabinet

Can a central controller be used for high-capacity battery rack applications?

These features make this reference design applicable for a central controller of high-capacity battery rack applications. Currently, a battery energy storage system (BESS) plays an important role in residential, commercial and industrial, grid energy storage and management. BESS has various high-voltage system structures.

How does the lmr51440 buck converter work?

The design uses the LMR51440 buck converter to convert the 24-V to 5-V power rail to supply the TMDSCNCD263, isolated power module UCC12050, and transformer driver SN6505B with a maximum 4-A capacity. A wakeup trigger circuit is designed to enable the LMR51440 from shutdown mode.

Which devices are used to implement isolated RS-485 communication function?

The UCC12050 and ISO1042 devices are used to implement the isolated CAN communication function. The SN6505B and ISO1410 devices are used to implement the isolated RS-485 communication function. The ISO1410 can support up to 500Kbps data rates. The design uses TPS3823-33 for timing supervision with a watchdog time out of 1.6 s. Figure 2-2.

What is a ucc12050 power module?

The device is available in the SOIC-16 (DW) package and a smaller SOIC-8 (DWV) package. The UCC12050 is an automotive qualified DC/DC power module with 5-kVRMS reinforced isolation rating designed to provide efficient, isolated power to isolated circuits that require a bias supply with a well-regulated output voltage.
