I'm developing a power supply circuit which has high and low voltage and a common ground. I have isolation of the switching control line via an optoisolator and a separate low voltage power supply. See attached circuit.
The remaining linking factor is the common ground - I have placed a diode to block any current flowing into the low voltage section.
Alternatively I could remove the linking ground connection all together.
Any thoughts on making this safer would be appreciated.
