Description
- STEVAL-IHT008V1, Evaluation Board limits the inrush current charging a DC bus capacitor so that it is compliant with the IEC 61000-3-3 standard. This inrush current is based on a soft-start procedure for the rectifier bridge achieved with a TRIAC added in series with the mains line, which is controlled through progressive phase-control during the startup phase. This solution drastically reduces standby losses as the DC bus can be totally disconnected from the AC mains when it is not required. The DC bus is easily turned off by turning off the series TRIAC, without needing an additional relay to open the circuit in standby
