"I have been using life batteries in my USV. Best reason to do so is you can get them on a commercial flight without problems. I had custom packs made, this allowed for smaller form factor in the battery box. This is important when the USV is toted…"
"If you go with active feedback then all you need is a 3P rectifier and a filter cap to convert back to DC. As the voltage drops the feedback loop "speeds up" the ESC and the Subsea output goes up. Very simple feedback. Converse when the DC voltage…"
"Tom,
Correct MATE Explorer class is allowed 48Vdc with current limit for power through the tether.
Ranger is limited to 12Vdc.
I have been working on Matt to allow AC in the tether circuit but limit it to 36v and apply a current limit as well,…"
"Good success with very long power delivery using Variable frequency 3 phase AC with active feedback.
A small onboard battery for surge loads that is recharged when the power load is low. (Capacitors can be used as well but a battery has a higher…"
"Just new here, but not new to the world of ROVs.
MATE is a program where a wide range of students design, build and compete at regional and international competitions.
