Serial #1:
(only passive portion of circuit assembled.)
w/Itest = 89mA (mV) voltage across (.47ohm) is: 2.5 5.7 1.4 2.3 2.3 1.3 3.0 2.0 14.8 1.8 R6 R7 R8 R9 R10 R5 R4 R3 R2 R1
Circuit voltage with test current:
- 1mA 27.8V
- 10mA 28.04V
- 100mA 28.6V
scope captures
[1] [2] [3] ~35 volts on 10,000uF cap applied to circuit via circuit breaker.
- blue is voltage across V+ and V- at array input
- other traces are voltage across the 0.47 resistors.
[4]
[5]
~35 volts on 10,000uF cap applied to circuit via circuit breaker.
- green is the voltage across the 10mF cap
- blue is voltage across V+ and V- at array input
- magenta is voltage across 0.47 ohm resistor of strongest clamp TVS
- difference between blue and green trace is the voltage drop across 12" of 14 AWG wire.
- peak total current is estimated to be 53 amps
