Intelligent Power Modules (IPMs): Concepts, Features, and Applications

Intelligent power modules are directed primarily at the high-voltage market. "High" is a relative term; in the parlance of low-voltage engineers such as myself, 50 V might qualify as "high," but that''s actually very low in the context of IPMs. For example, the lowest maximum voltage rating in Infineon''s CIPOS Nano family is 40 V.

String fuse requirements

In string inverter systems, a line-line fault can create a critical reverse current. To protect the PV modules, string overcurrent protection is necessary if the PV module rating is insufficient. However, even with string fuses, when the current is lower than the module rating there is a current at the fault location, and it may cause a fire.
