Product Specifications

Technical details and manufacturing context for Energy Storage Converter (PCS)

Definition

The Energy Storage Converter (PCS) is a critical component in battery energy storage systems (BESS), used in renewable integration, peak shaving, frequency regulation, and microgrids. It is specified by power rating, voltage range, efficiency, and grid compliance. Grades differ by efficiency, response time, protection features, and grid code certifications.

Working Principle

The PCS uses power semiconductor devices (IGBTs) in a voltage-source converter topology to convert DC from batteries to AC for the grid and vice versa. It controls the switching to regulate voltage, current, and frequency, enabling bidirectional power flow. Advanced control algorithms ensure grid synchronization and power quality.

Common Materials

IGBT modules, Aluminum electrolytic capacitors, Ferrite core inductors, Copper busbars, Cold-rolled steel enclosure
