Anybody help me, know how this voltage generator works. does it change 14.5v - 18v to 100v-400v in pulse or just constant voltage?

The high voltage is generated by the grey box, bottom right of the diagram, labelled 'voltage generator'.Here is the thing. You cannot get more power out of a circuit than you put in. So the input voltage is 14.5 to 18 Volts and you want to get say 300 Volts out. I don't see current mentioned anywhere. Let us be modest and say we want 300 Volts at 1 Ampere. That is 300 Watts of output power. Again let us be charitable and say the conversion process is 80% efficient. That means the required input power is 300 watts / 0.8 = 375 watts. Assume our input was 14.5 Volts that means we need 375 / 14.5 ≈ 25.9 Amperes. It does not matter if this is pulsed or continuous - required power is required power. Boosting a DC voltage, by any means, means reducing the available current. You can't get something for nothing.
The circuit pulses the high voltage at variable frequency and variable pulse width.Anybody help me, know how this voltage generator works. does it change 14.5v - 18v to 100v-400v in pulse or just constant voltage?
Using an isolating transformer, that blue MOSFET would be unable to turn the high voltage on and off, therefore no pulses.With isolating transformer, I think the circuit itself, with voltage adjusting pot can increase voltage evenly high, if the transformer provide only 120v . let's assume, I use step down isolation transformer 240v/120v
