Bidirectional 3000W UPS Power

Overview

This system is designed for telecom DC uninterrupted power supply (UPS) applications. New telecom UPS applications are utilizing Li-ion/Lead-carbon batteries to replace the original Lead-acid ones. As a result, they will need a platform capable of either charging the battery or powering the traditional -48V telecom system. Our system includes high-performance buck-boost controllers, MCUs, and power devices to achieve bidirectional power conversion, making it a competitive option.

System Benefits:

  • High-performance buck-boost controller allows for high-performance bidirectional power conversion.
  • Renesas hardware and software support enhanced platform competitiveness.
  • Our system is designed to simplify and expedite the development process, reducing time to market.
