AI Thread Summary
A Pulse Forming Network (PFN) can charge a capacitor to high voltages, but the discussion raises questions about voltage multiplying PFNs that do not utilize switches or spark gaps, with Marx generators being the only known type that does. There is curiosity about whether repeatedly discharging a PFN into a capacitor could elevate the capacitor's voltage beyond the PFN's output voltage. Additionally, the potential for the PFN's inductance to function like a flyback transformer to produce high voltages is explored. Participants are encouraged to share resources for further learning about PFNs. Understanding these concepts is crucial for effectively using PFNs in high-voltage applications.

I am trying to understand how a PFN (Pulse Forming Network) could charge a capacitor to a high voltage and I have some questions first.

Is there any type of voltage multiplying PFN which does not use switches or spark gaps?
(The only type I have seen is the Marx type which uses either switches or spark gaps to generate a high voltage output)

If a PFN was repeadetely discharged into a capacitor would the capacitors voltage increase beyond the PFN's voltage?

The last question I have is, could the inductance of the PFN act as a flyback transformer to generate high voltages?

Thanks everyone.

Could you please supply some learning links to this PFN subject? I haven't seen it before. Thanks.
 
Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
