Description

This is a test I did to verify to Volt drop on Graetz Bridge (GBJ1504) using a load of different values.

  • < 1k we assume Vd=1.25V
  • 1k < R < 10k we assume Vd=0.85V
  • > 10k we assume Vd=0.5V

Tests

R=100K Vr=11.595V I=115uA Vd=0.202V Vg=0.404V

R=10K Vr=11.317V I=1.132mA Vd=0.341V Vg=0.683V

R=1K Vr=11.031V I=11mA Vd=0.485V Vg=0.97V

R=500 Vr=10.944V I=22mA Vd=0.528V Vg=1.05V

R=100 Vr=10.734V I=107mA Vd=0.629V Vg=1.258V

R=10 Vr=10.448V I=1.04A Vd=0.775V Vg=1.55V
