Motor Brakes

Motor Brakes

Description

Motor breaks are used to protect the DC bus and power stage from over-voltage and coasting. When the AC drive is braking and feeding energy back into the DC bus, this is where a motor brake can be utilized. The brake module is connected to the DC bus and may be a part of the AC drive, power stage, or a separate module. Located on the brake module is an IGBT power switch, non-isolated or isolated gate driver, and an external mounted resistor which serves to dissipate braking energy to heat in the case of the DC bus exceeding the specified threshold.

The following TI solutions assist in solving system design challenges:

  • Isolated and non-isolated IGBT/SiC/GaN FET gate driver with high CMTI, built-in protection and capability to drive large IGBT
  • High efficiency power supply solutions for various topologies such as quasi-resonant fly-back and fly-buck
