Hello SMPS builders
This is my last switchmode power supply. I build it with 2 inches toroidal transformer, half bridge topology, 4 IGBT output, optozener regulated (+43/-43VDC), if regulated less it work in +66/-66VDC. SG3525 PWM controller transformer direct drive, buffer less, now, to wait a new-next power amplifier.
Comments are wellcome.

As an ex SMPS designer I was tempted to say same but didnt but now I will. Needs at least 8 mm creepage and clearance between input and output (including across opto / isolation barrier and any swtiching XFR) and 4mm or more betwen L and N / L and E. Of course if its for private use you can do as you wish but if you are 'advertising' the design then I would strongly suggest putting a warning on it to protect yourself. regards A Streeter
