In accordance with the current international requirements [4-6], for simulating the direct lightning strike, it is necessary to check the reaction of the GD to the pulse voltage
of 1.2/50 [micro]s and the current pulse 10/350 [micro]s, and to simulate the pulsed currents induced in the metal structures and communications of the object with distant lightning strikes--8/20 [micro]s.
The output signal voltage at the pickup coil was monitored by continuously varying the driving pulse voltage
to the soft magnet.
In order to generate excitation pulse current when U phase current transits from positive to negative, inputting positive pulse voltage
when U phase voltage turns OFF and inputting negative pulse voltage
when W phase voltage turns ON are needed.
A form of non-volatile memory in which a pulse voltage
is applied to a metal oxide thin film, creating massive changes in resistance to record ones and zeros.
1(a)) a basic circuit of a diode connected to a pulse voltage
source is shown and in Fig.
Electrochemical anodization was carried out with a pulse voltage
The value of the bipolar pulse voltage
was 4 kV, and the frequencies were 300Hz, 500Hz, 600Hz, 800Hz, and 900Hz.
The circuit of the pulse voltage
generator used in this study consisted of the pulse-forming capacitor (20 nF), charged through a 50-kilo-ohm resistor by a negative DC high voltage power supply and rotating spark gap switch.
Here, the spectra from the deposits created by the pulse voltage
