IGBT Motor Controller Protection

Problem: Voltage and Current Transients

The IGBT motor control equipment can be put at risk from large voltage or power transients on the AC inputs due to diode/transistor malfunction, or miswiring or dielectric breakdown of load and from the resulting surge currents.
 

Solution: LVR + ROV

Synergies between protection devices can be overlooked as overvoltage and overcurrent protection are often viewed as completely unrelated conditions. With PolySwitch LVR devices and Raychem Metal Oxide Varistors (ROV), Tyco Electronics offers designers a complete solution that helps enhance product protection and reliability.
