Bidirectional CLLLC Resonant Converter Reference Design for Energy Storage System

Description

The capacitor-inductor-inductor-inductor-capacitor (CLLLC) resonant converter with a symmetric tank, soft switching characteristics, and ability to switch at higher frequencies is a good choice for energy storage systems. This design illustrates control of this power topology using a C2000® MCU in closed voltage and closed current-loop mode. The hardware and software available with this design help accelerate time to market.

Features

  • Vprim: 380–410 V DC; Vsec: 40–60 V DC
  • Power Maximum: 3.6 kW, 97.6% peak efficiency
  • Soft switching with Zero Voltage Switching (ZVS) on the primary, Zero Current Switching (ZCS), and ZVS on the secondary enable higher efficiency
  • Active synchronous rectification scheme implementation using Rogowski coil sensor enables higher efficiency
  • Software Frequency Response Analyzer (SFRA) and Compensation Designer for ease of tuning of control loops
  • Software support for the TMS320F28004x device with the Control Law Accelerator (CLA), which enables integrated power conversion system design with AC-DC and DC-DC controlled using a single C2000 MCU

Applications

  • Battery energy storage system
  • Power conversion system (PCS)
  • Portable power station
