SIGMA22 +/-35V To 80V Dual‑Rail DC high power linear power supply board for amp
SIGMA architecture with +/- 35V~80VDC 8A high-power power supply, dual SIGMA22 high-power DC stabilized power supply.
Based on the SIGMA22 V3.0 architecture improvement, we communicated with the original author of AMB on the forum and came up with an improvement plan. The reference voltage adopts dual transistor stabilization, and the high-power output uses two pairs of TO-247 packaged high-power transistors IRFP240 and IRFP9240 in parallel, ensuring almost no voltage drop in high current scenarios. The optimal output and output voltage difference is 4V-10V, and it is important to pay attention to heat dissipation!!!
