How can I convert a 113B13 transformer to a center tap transformer? Is like this, for example: - primary coil: 1 and 2 pins. - secondary: 3 and 6, where 4 and/or 5 is the center tap? Will this work?

  • \$\begingroup\$ Why would you need a center taped pulse transformer? Show a schematics of this particular use. \$\endgroup\$ – Marko Buršič Feb 20 '17 at 14:58

Connect pins 4 and 5 together, and it becomes the center tap. Between 1 and 2 would then be the primary.

  • \$\begingroup\$ @Arttu: Do you understand what ratio the center-tapped transformer will have? \$\endgroup\$ – Oskar Skog Feb 20 '17 at 15:02
  • \$\begingroup\$ @OskarSkog I will use for "Royer inverter". I have 113B13 which is 1:1:1 itself. By using 3-6(with 5 and 4 as center tap) as a primary and 1-2 as secondary it will become 2:1 step-down transformer. So, if I need a step up transformer I need to increase the number of turns on the secondary. That I think about it. \$\endgroup\$ – Arttu Feb 21 '17 at 16:14
  • \$\begingroup\$ That's correct. Just had to check that you weren't going to do something stupid. \$\endgroup\$ – Oskar Skog Feb 21 '17 at 16:38
