I'm using a half bridge for my DRSSTC. The reference schematics is from eastern voltage research.

I'm not using a voltage doubler since we use 240 V lines here. Where should i connect the end of primary marked in red circle:

1. + or - on main bus cap
2. Neutral wire of 240 VAC

Kreso,

The confusion is because dan uses a voltage doubler where the lytic center point connection is also line neutral. There is no reason in particular to connect the primary to the center point of the 2 caps, the + or - rail works just fine as well.

Do NOT connect the primary back to the AC power input, that would be very bad.

I thought like this and after you confirmed me i was sure. But Dan said other way
