|
|
3.70 - excitation from one battery (3.7V)
|
||
|
|
7.40 - excitation from two batteries in series (7.40V)
|
||
|
|
In no case the current from excitation is allowed to go above 2A. In no experiment the current is observed to be above 1.5A.
|
||
|
|
The results in tables are output voltages measured at 1000:1 HV probe, hence the output voltage is given in kV.
|

|
|
Flyback configuration with TIP122 NPN transistor with 330 Ohms resitor in base is used.
|

|
|
Single cascade is used with 30 capacitors and 60 (30x two-in-series) diodes 1N4007.
