Product Description
ESS PCS-250-T Power Conversion System Isolated Energy Storage Converter
A Power Conversion System (PCS) is the central power electronics component designed for efficient energy form conversion and control. Its primary functions include:
-
Bidirectional Energy Conversion: Seamless DC-AC and AC-DC transformation (e.g., battery storage-grid interaction)
-
Dynamic Regulation: Real-time control of voltage, frequency, power factor (compliant with IEEE 1547)
-
System Integration: Intelligent interface among renewables, storage, and grid
2. Technical Architecture
2.1 Core Subsystems
| Module | Function | Key Technologies |
|---|---|---|
