I know this is old , but I find the figure quiet interesting , the source pin of the mosfets met at 2 point , point 1 switch node where main current is passing and point 2 is at the gate driver leg . doesnot that make a loop / antenna and radiate noise ? doesnot that also welcome the switching...

unrelated question ,. you always emphasize on the idea of traces running through power section and routing gate/return in differential pair or kelvin connection i donot remember . How can you apply those principles when you have mosfets in parallel ?

what happened did the patent come through ? are you going to share your board design ?

thanks for taking the time to answer. I do understand your point about not opening the project i hope it will turn out some profit for you if you start selling these . you have shared quite a lot of info I didnot know that the new boards are IMS . which is why my question about bulk caps is...

its sad that you decided against open sourcing the hardware especially the power board. Even if people did not build the board because lack of funds or semiconductor shortage , Later someone will sure build it or use the ideas in their own designs. It has been a pleasure reading through this...

thank u for taking the time to reply. Regarding power consumption i was referring to the HV version since it contains a contactor and those consume at least 2w to stay On which is nothing when drawing hundreds of amps but huge if you are in standby. So my question is really how does the...

amazing work really If i am ask i have 2 questions: 1. Is there a method to make it work with 12v (4s) or 24v (8s) batteries ? 2. what is the standby current consumption ( no load / no charging ) ?

Hi I am planning on converting a 250cc ATV to electric , I want to install a ME1114 PMSM motor and was thinking about using the new kelly KLS-8080I/IPS controller to match it. but my experience with old kelly dc controller is bad and i hear a lot of people share the same thought. If anyone...
