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.
