Vectatus update
Added 2025-02-12 12:26:42 +0000 UTCVectatus now has programmable voltage snubber that can be adjusted from 100% to 0% to suit very voltage sensitive applications or inductive loads like motors that generate high voltage transients.
Also the output voltage ripple can be programmed. Once the max output voltage ripple is detected the snubber algorithm gets engaged.
In fact the soft boot ramp up and speed can also be programmed. :)
This is really cool, to have ability to control the DC/DC conversion with such a granularity, and I am sure many new power algorithms can be build on such platform. For example it might be possible for Vectatus to learn about the load during operation and auto-adjust all the parameters.
Not only that, but there are additional, programmable, application specific protections like over-current or over-voltage protections that once triggered, will make the Vectatus enter error mode. This mode remains until fault is removed, and user presses any button. Then the last operating mode gets started again (with soft-boot of course).
Firmware uses watchdog running in 2ms interval, so if there is any hangup that takes more than 2ms the board will reset itself, and due to SEPIC topology the output will be disconnected completely.
Moreover I've tested output over-current and short circuit protection and it is working!
