Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

Hi Jeg, that should not be a problem. The inputs to the L298 board are digital CMOS/TTL compatible inputs so they consume no current, typically 10-30uA per input, see the datasheet:

Thank you PMGR. Indeed 10-30uA is nothing. I was trying to find a good opto-isolator for the inputs when i realized this 200mA limit.

Don't forget options.. as a relay replacement.  http://www.crydom.com/en/

Those Crydom SSRs seem to be selling for between about 12 and 20 dollars US each, depending on ratings and quantity purchased. So say you need 72 of them to replace Pierre's relays.... Well, nobody ever said Free Energy would be cheap, I guess.

Who is going to spend that kind of money on something where the original claims are still not verified?

For this application a jarfull of cheap SMD mosfets, mosfet drivers, and a custom-designed PCB could probably be built to handle all the switching for under a hundred bux (estimated of course). The major time consumer would be designing the PCB and sending the design off to a fab house in China.

Why buy. You can do it cheaper 2$


For example: DIY
AC and DC version:

A 12 step simulation now at 52 Hz. N.b. wave  voltage drops suddenly!

Compared with the 5 Hz version the total Amperage draw don't decrease so much !
