Overview

The IRMD26310DJ is a reference design kit for the IRS26310DJ three phase gate driver IC with integrated

bootstrap functionality and DC bus overvoltage protection. The design kit includes a complete drive system board

with an input rectifier, control power supplies, digital motor control IC and power inverter. Safety features include

protections against motor line-to-line, line-to-DC Bus(-) short situations & DC bus overvoltage conditions. The

power stage features the IRS26310DJ gate driver and six discrete IGBT power switches allowing for easy

customization. The included PC based GUI software allows the user to drive an Induction Motor in open-loop

Volts-per-Hertz mode of operation using the on-board digital control IC. The motor speed and system parameters

such as PWM frequency and deadtime can be modified using the GUI. Alternately, the IRS26310DJ gate drive

input PWM signals can be supplied externally by patching in signals through an on-board connector.
