In
waveform Ch1 is the voltage of D8A anode referenced to the secondary ground potential,
while the waveform CH3 shows the current flowing into D8A-D10B diodes. Also this current
waveform (like the one flowing into the resonant tank at the transformer primary side) has
almost a sine shape, and its average value is one half the output average current.
Thanks to the advantages of the resonant converter, the high frequency noise on the output
voltages is less than 50 mV, while the residual ripple at twice the mains frequency (100 Hz)
is about 150 mV at maximum load and worse line condition (90 V
