Hi,
In schematic of TIDM-BIDIR-400-12 (tidrhs9.pdf), there is external capacitor charging circuit as below. It is written as active clamping.
1) Why is there need such a circuit, how does it operates? Please, guide me if any document available.
2) Does it work on HV-to-LV or in reverse?
3) Is there any future plan adding this clamping feature to software?
Thanks.
