PCS100 G 125 3S Modular Energy Storage Converter Battery For Integrated High-Voltage Box

Modular Energy Storage Converter (MESC)

1. Technical Definition & Core Architecture
A Modular Energy Storage Converter (MESC) is an advanced power electronics system designed for intelligent energy management in modern power networks. Its architecture consists of:

1.1 Power Conversion Subsystem

Bidirectional AC/DC and DC/DC conversion capability (Topology: Typically 3-Level T-Type or NPC)

Wide voltage range operation (400V-1500V DC, 380V-690V AC)

96-98.5% peak efficiency (CEC weighted)

1.2 Modular Building Blocks

Standardized power modules (25/50/100kW per module)

Hot-swappable design with <5ms transfer time during replacement

N+1 or N+X redundancy configuration options

1.3 Control System

Hierarchical control architecture:

Primary: Droop control for power sharing

Secondary: Voltage/frequency regulation

Tertiary: Economic dispatch (convex optimization algorithms)

<500μs inner loop control period

2. Technical Advantages Analysis

2.1 Scalability

• Power scaling: 100kW to 20MW+ through parallel connection
