ACFL-3161: TO-247 SiC MOSFET EB1200-3161 Evaluation Board

Overview

TopologyOther Topology
Input voltage15 V
IC revision1.0

Description

Evaluation board EB1200-3161 features Broadcom® dual output isolated gate drive optocouplers, ACFL-3161, that drive SiC MOSFETs in a discrete TO-247 package. The board features an integrated capacitor DC Bus with optimized layout that minimizes the commutation loop inductance and shunt-based source current measurement. The EB1200-3161, shown in Figure 1, is developed to support Broadcom customers during their first steps in designing power converter applications with ACFL-3161 drivers. Properties of the board are described in the following sections.

Features

  • Two isolated ACFL-3161 gate drive optocouplers with following features:
  • UVLO (under voltage lockout) protection
  • Dual output drive to control turning on and off transients
  • Electrically and mechanically suitable for TO-247 4 pin packages
  • With adjustment of the gate resistors and isolated auxiliary power supply, the evaluation board supports the following SiC MOSFETs:
  • STM SCTWA70N120G2V4
  • Wolfspeed C3M0021120K
  • DC Bus and balancing/discharge resistors
  • Isolated SMPS for gate drivers
  • Resistor shunt-based, low side switch current measurement over the BNC interface
  • Access to PWM input signals.
  • Continuous operation in buck/boost configuration up to 3-kW output power and 50-kHz switching frequency. The user must provide and integrate an appropriate heat sink in case of continuous operation.

Typical applications

  • Renewable energy inverter and storage
  • Motor drive for industrial automation and robotics
  • Power supply and battery charger
