描述 Description

The STEVAL-SCR002V1 introduces a simple and innovative AC-DC front-end circuit

that allows the designer to perform an inrush current limitation in any converter with

input rectifier bridge topologies.

Based on a discrete control circuit made of one Z0110MN SMD triac and two

STTH110A diodes, it offers a compact and non-insulated high voltage driver for the

mains SCR. The drive circuit synchronizes the SCR gate signals with the AC line

polarity and powers directly the SCR gate from the mains. This operation does not

generate reverse losses in the SCRs.

This STEVAL-SCR002V1 solid-state solution provides a high reliability, a long service

lifetime, an electromagnetic interference reduction, and a faster response compared

to electromechanical solutions.

This solution is also compatible with an inrush current limitation performed either in

the NTC/PTC bypass mode or in the MCU phase-control mode.

The enable control pin of the SCR driver is referenced to GND_DC. Therefore, an

uninsulated power supply or a direct control by the MCU can be used.

With five wires to connect, the STEVAL-SCR002V1 is designed for an easy

implementation on existing AC-DC converters for plug-and-play tests.

It is suitable for applications with an RMS current up to 4.3 A (at an ambient

temperature of 60°C).
