This regulated power supply was built as a simplified outboard version of a PSU in my first phono stage. Replacing hexfreds with tube rectifier eliminates the need for power-on sequencing. Chassis (salvaged from a hospital laser PSU) size is 180W*240D*100H mm with a 125W double-C core power transformer and a 10H/100mA choke inside. Read More [...]
The circuit diagram of the flyback converter will hold no surprises (Fig.16). Literally the only difference with the boost converter is that the inductor is replaced by a transformer, and that the transistor has been replaced for a BUZ21. The BUZ21 has a much lower on resistance (Ron=0.085 ohm) as compared to the BUZ41A (Ron=1.5 [...]
