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

The diodes are wired 2 in parallel which is  a strange way to get the current rating doubled however, maybe its just cheaper doing it that way. The way its drawn ,the diodes look like they are either side of the switch each one joined a potentially different current flow.  Anyway they just are not connected that way.

There are two factors which make sense wiring transistors and diodes in paralel: lowering resistance and eliminating generated heat.
Instead of wasting energy as heat I am also doing paralel diode connections in experiments when frequency and internal capacitance do not interfere.

Still the transformer needs 0.5 Amp when charging supercaps (via 4 Ohm)  and 1.5--> 2.5 Amps to the same primary when running the system. I can't believe that the thin wire I pointed at, feeding some or more  relays can handle 4-8 Amp at the secondary side while only a slight current goes thru and warms up, that super HOT 4 Ohm resistor. Look at the size of the wires to and from that resistor. We need a better explanation

the red wire is probably the common power for driving the relay coils.  Most relays require 15-20mA; and since only 3 or 6 relays are engaged at a time, only requires 45-60 or 90-120mA respectively.
