Hi guys , I've one answer. I've seen the schematic for vesc 75300, but anyone know what upgrade that schematic need for support 20s? The original chip INA240 can support max 75v I've seen, any solution?
There is a 100/250 avaliable already. https://trampaboards.com/vesc-100250--p-27368.html
shunts could be placed sources of mosfets and gnd
you can just use INA181 and place shunts on ground side.
Hi.
if (shunts could be placed sources of mosfets and gnd)
does need any change on code?
"#define INVERTED_SHUNT_POLARITY" may be needed to define as in hw config.
Just remove the line about HW_HAS_PHASE_SHUNTS and you should be good.
The caps should be upgraded as well.
