Design files

Overview

This reference design is a digital controlled 3.6kW power supply for energy storage applications with bidirectional power flow capability and soft switching. This design illustrates control of this power topology using a C2000™ microcontroller in closed voltage and closed current-loop mode. The hardware and software available with this design can help accelerate your time to market.

Features
  • Vprim at 380V to 410V DC and Vsec at 40V to 60V DC
  • Power max: 3.6kW with 97.4% peak efficiency
  • Soft switching with Zero Voltage Switching (ZVS) on the primary and Zero Current Switching (ZCS) on the secondary to enable higher efficiency
  • Active synchronous rectification scheme implementation using Rogowski coil sensor to enable higher efficiency
  • Software Frequency Response Analyzer (SFRA) and compensation designer for ease of tuning of the control loops
