‘AMP_ +/-B’ switch regulator-1b
CEMF charge path
In this circuit it, seems no current through D1107, but D1107 is high power Schottky Diode
with heat sink, If You mean with DC Volt meter but if you use Oscilloscope you can see the
negative peak is clipped. This clipping is by D1107
WHY? *DC METER CHECK
+B 70 V
ANP+B 30V
(+30 V) *
_
+
Because there is a large charge current through D1107 that forced by CEMF.
