Spletcurrent and voltage crossover losses at turn on under hard switched conditions. Fig. 1b shows the same waveforms with ZVS. Switching losses are eliminated as there is no crossover between V DS and I DS. In addition to switching loss, ZVS also minimizes the switching noise during turn on and associated EMI. Fig. 1a. SpletUS power is a bit less efficient in general because while we have roughly half the voltage devices still need the same amount of power so the current is doubled to compensate. This leads to transmission losses in the wires (loss = I 2 * R). But I don't see why this would persist into the power supply itself.
