On-demand Webinar: How to implement Overvoltage Protection and Inrush Current Limitation using Thyristors

How to implement Overvoltage Protection and Inrush Current Limitation using Thyristors Webinar

During this one-hour webinar, we will discuss the use of thyristors, also known as silicon-controlled rectifiers (SCR), as active elements in limiting inrush current into the inputs of AC/DC converters with PFC.   Also, the implementation of Overvoltage Surge Protection for AC-DC Applications. 

With voltage ratings at both 600 V to 1200 V, ST’s 150 °C rated SCR portfolio enables precise control of AC line inputs to a wide variety of power levels and topologies. In particular, the ability to control the inrush current into AC powered supplies at > 1 kW is a key application of these niche devices. We will review why and how this is such a beneficial technique for the power supply engineer, especially for the latest in bridgeless PFC topologies.

We also introduce the ST SCR based in-rush current limiter solutions to replace the relays with active silicon and removing the current limiting NTC.  

You will learn:

  • What is Thyristor SCR
  • Overvoltage Protection
  • Why use Inrush Current Limiting (ICL)
  • Inrush Current Limiting (ICL) Smart Solution
  • Resources - Evaluation Boards & Application Notes
