PWM for contactor

Post by madius »

Hi!

I am migrating a 50V golf cart controller to openinverter with a bluepill.
The original controller was driving the main contactor with a PWM signal at 70% since it is 36V.
Is there any possibility to configure that in openinverter?

Thank you very much

No, it is just on/off, you'd need to use some economizer IC (DRV103). Also look here: https://openinverter.org/forum/viewtopic.php?t=531
