Isolated IGBT and SiC Driver Bias Supply Reference Design for Traction-Inverter Applications

Overview

TopologyLLC Resonant Converter
Input voltage24 V
Output 120 V / 0.3 A
Output 2-4 V / 0.3 A

Description

This isolated open-loop LLC transformer driver converter provides dual +20-V and -4-V outputs up to 6 W for traction inverter applications. The 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. This reference design offers a high level of integration and high efficiency in a compact form factor.

Features

  • Open-Loop LLC transformer driver
  • Ultra-low EMI
  • 9-V ~ 34-V supply range
  • 6-W output power with 24-V input
  • Resistor programmable switching frequency from 100 kHz to 1.2 MHz
  • Synchronization to external clock
  • Programmable maximum dead-time with automatic dead-time adjustment
  • Under voltage lockout
  • Adjustable over-current protection thresholdExternal disable function
  • Input over voltage protection
  • Over temperature protection (TSD)
  • Fault-code output for system intelligence
  • Latched and fault-auto-restart versions available
  • 8-Pin DGN package with thermal pad

Typical applications

  • Automotive traction inverter,IGBT and SiC gate driver bias, Automotive DC/DC,automotive on-board charger, EV charging station, automotive super charger, UPS and solar inverters, Industrial motors, elevators, and escalators.
