    Capacitor charging

    Maybe a transformer with a greater turns ratio?

    Capacitor charging

    What capacitance/voltage should have the ceramic Cap for the test ? I could try another electrolytic Cap a 330V 160uF until i get the ceramic one.

    Capacitor charging

    Capacitor electrolytic leakage- discharge of current between Cap plates when charged but with no load, that's not too hard to understand.

    Capacitor charging

    Well i know what the voltage and capacitance of a Cap is but don't know about Cap electrolytic leakage, i did something else i removed the Cap entirely to see the inverter voltage it goes up to 30V and that's it.

    Capacitor charging

    Thank you for the info, I checked the cap voltage with a second voltmeter with 1000V setting, it charges very slow above 200V I usually stop it at 230V because it takes ages for 1 volt, the yellow button starts the charging process you have to press it continuously to charge, the red one...

    Capacitor charging

    I don't have a circuit diagram, i bought that kit and it was working with a 250V capacitor and I switched to 400V, when you say inverter that's the transformer + transistor + resistor ? I have no idea how much voltage produces the invertor I am a novice in electronic circuits.

    Capacitor charging

    So that transformer might be the cause why I can't charge the 400V capacitor to more than 220V.

    I don't have a schematic I received that kit, is the red pointed component a transformer? it has 4 pins. upload images

    Capacitor charging

    Its a old picture with the 250V Capacitor but now i have a 400V one, so how can I increase the inverter voltage with the same 4x 1,5V batteries?

    Capacitor charging

    I can't run out of psu i am using 4x 1,5v batteries, my guess is I need to replace the transformer or a resistor.

    Capacitor charging

    Hello ! I have the circuit from the picture below and a 400v 1000uF capacitor, the problem is from 200V up the charging is going very slow and it stopes at 230V, any ideas? I want to charge it at least to 350V. Thanks! image hosting 10mb limit
