Voltage doubler using 555 timer

I found this circuit, a voltage doubler with 555. The duty cycle of the 555 is 50%. Does changing the duty cycle of the 555 timer affect the voltage output like in boost converter? Or does it not change anything except the charging rate of the…

Confused with voltage doubler circuit

This is how the book explains the process: Let me consider the first 90° of the input, the capacitor charges up to the peak voltage less the diode drop of D1, D1 is forward biased and D2 is reverse biased, that's ok, but what I don't understand is,…

charge pump doubler

I am not fully sure as to how this circuit works. I know that during the positive half cycle D1 is on and C1 charges to V volts, and that during the negative half cycle D1 will become off and D2 conduct. So some charge flows from C1 to C2, keeping…

Choosing capacitor value and rating and diode rating for Cockroft-Walton circuit

I am building a voltage multiplier Cockroft-Walton circuit that produces around 120 kV output voltage with 15 kV input voltage (initially 250 V is stepped up to 15 kV using transformer). I have not been able find a resource that guides me on the…

How ca I match a class AB amplifier to voltage multiplier through a transformer?

So here it goes, I will keep this issue as simple as possible. I have this Class AB amplifier over here, that brings me a 60 Hz sinusoidal signal up to aprox 15Vp. Must be said that the sinusoidal wave is being generated by PWM and a MFB 2nd order…

Help with circuit (voltage doubler)

I need some help with the following circuit: I simulate it using LTSpice IV and have this: But I couldn't get that thinking. Of course, I know that it's possible that there's some DC voltage before the capacitor C2 if it's Ground on the other…

Manufacturing precautions for voltage multipliers

I've been watching YouTube: https://youtu.be/YYKlfFYTl-8. Can you tell me is this dangerous or not to do at home? So I've been watching this video, and I've wanted to do it myself, but to the number 67000V is scary. I looked up what is the upper…

How do I triple the output voltage of a 555 timer boost circuit?

I currently have an output of 160V, but my application requires a minimum of 400V-500V. Is there a method to triple the existing 160V to achieve the desired voltage range of 400V-500V?
