Vd of the rectifier seems to be WAY off, the "normal" diode config is too confusing for me.
I might be missing something simple, like how Vd of any diode is marginally influenced by the aamount of passing current.
It is supposed to simulate a 5V line, fullwave bridge rectifier IC (primarily to drop voltage but added safety is nice), 1W LED with 3.3 V Vf and 330mA If and a current limiting resistor which I want If to be ~ 250mA to avoid full If(/brightness/heat dissipated) but this shows a current around 100mA.
Not sure how accurate this is compared to the real world but I intend to find out (probably resulting in thermal runaway since my old 1W LEDs came without heatsink/PCB).
