Ultra-low EMI transformer driver for isolated bias supplies

Overview

TopologyLLC Resonant Converter
Input voltage9-34 V
Output 12.5 V / 0.96 A
Output 218 V / 0.13 A

Description

This reference design is an open-loop LLC converter, which provides four 18-V and 2.5 V outputs and up to 2.4 W for onboard charger applications. UCC25800-Q1 is used as the controller. LLC topology allows the transformer to have significant leakage inductance, but a much smaller primary-secondary capacitance, which significantly reduces common-mode current injection through the bias transformer.

Features

  • Small size open-loop LLC
  • Reinforce insulation
  • Compact PCB size (55 mm * 45 mm)

Typical applications

  • GaN, IGBT and SiC gate transformer driver bias supply
  • Industrial motors, elevators and escalators
  • Automotive traction inverter & motor control, Automotive DC/DC converter, Automotive on-board charger (OBC), EV charging station, DC fast charging station
  • UPS and solar inverters
