Hello
i need to design two Isolated power supplies - can you suggest the best design option(s) to use. As where I can get assistance to design the transformer
POWER A - “HH” module:
IN: 115V 400Hz CURRENT IN max 0.6A rms
Approx max power requited: 60 W: (assuming > 85% eff.)
OUT 1: +/- 120V DC, 0.2A rms (for POWER Amp)
OUT 2: +/- 18V DC, 0.2A DC ( Power for driving IC power: +/-15 for DAC, +10V Ref for one DAC, 3.3 V for logic)
OUT 3: +/- 18V DC 0.4A DC (must be isolated from OUT 1 & OUT 2) ( will be used to produced regulated +15V for Display, +5V for USB, +3.3V for Logic)
POWER B - “LL” module:
IN: 26V 400Hz / Max 1.8A rms
Approx max 47 W: (assuming > 85% eff.)
OUT 1: +/- 20VDC 1.5A rms (for POWER Amp)
OUT 2: +/- 18V DC, 0.2A DC ( Power for driving IC power: +/-15 for DAC, +10V Ref for one DAC, 3.3 V for logic)
OUT 3: +/- 18V DC 0.4A DC (must be isolated from OUT 1 & OUT 2) ( will be used to produced regulated +15V for Display, +5V for USB, +3.3V for Logic)
