4800 watt construction heater wiring - partial voltage explanation - Attn Troy
However, everything doesn't work perfectly. Diodes in a large power circuit
do heat up and need to be cooled.

(in article ):
Getting pulsating DC by adding a diode to the circuit chops off either
the
upper or lower half of the sine wave, losing that as heat.
Not really, the diode is the electrical equivilent of a check valve. No
current flows back through it so no heat is generated. An ideal diode has
zero forward voltage drop and infinite reverse voltage drop but dissipates
zero energy.
