Hi,
I've got a set up I've been playing around with running for a mobile work shop application.
2X 24 V, 6 A motors
1X 12V car battery
2X Gecko 203V's.
1 Step-Up 12/24V DC converter rated for 300 W, 12.5 Amps output continuous.
Having some issues with the drives quiting at high speeds steady state when both motors are running. I've seen improvement by adding 470 uF caps to the drive inputs, but no improvement by adding a 10000 uF to the Step-up converter output. I guess following the
C = 80000*I/V thing this should be more like 40000uF, but I'm wondering if it's more I'm pushing the limits of my step up converter and that's what's causing the drives to shutdown, but I think it might be something else.
I've also tried subbing in a 12V 20 A regulated power supply for the battery and seen similar problems.
Thoughts?
