Finally, the opto-coupler could be connected directly in high side mode between the SYN and the V
pins: the ZVS signal is then made of high level pulses synchronized with the zero crossing. However, the
coupler could be connected in low side mode with an external 10k pull-up resistor to V
inverted with low level pulses.
