DETAILED DESCRIPTION
PWM Transformer Mudule use 139T6325 toroid with 2.100 gaus, 3,06 Ae. This toroid support 3.200W at 24 kHz (5.000W at 37 kHz).
For 3,06 Ae toroid at 27kHz and Half-Bridge PMW, transformer turns is:
- Primary: 28 - 3 wires AWG 23
- 12v: 2 (x2) - 2 wires AWG 20
- 30v: 5 (x2) - 3 wires AWG 20
- 36v: 6 (x2) - 5 wires AWG 20
- 54v: 9 (x2) - 5 wires AGW 20
I am using 2x 9 turns with 5 wires AWG 20 each, with outputs at turns 2, 5, 6 and 9 for 12v, 30v, 36v and 54v.
+/-12v and +/- 54v outputs is full bridge rectifyer.
+30v and +36v is one diode at each wire (one double diode - CT - for 30v and other for 36v).
Using 2x 9 turns 5 wires AWG 20 (same wire to all outputs), maximum power estimated in secundary is 2x 54v x 20A = 2.160w.
-> This module was designed to be used as sound amp power supply.
Works with other 3 modules:
- AC/DC Bridge rectifyer Module
- PMW Control Module
- DC Filter Module
