    One thing that might confuse viewers...the second stage serves to smooth the ripple and is not necessarily required, such as with microwave ovens. You double the voltage with one stage (c1 and d1). It's a point of confusion you did not address. Otherwise great video.

    Rectified voltage becomes the peak value of AC when using capacitors. In other words 240VAC measures at almost 340VDC, or in this case, 12VAC will measure at around 17VDC (less the diode drop.) Thanks for not adding music, btw.

    The current will inherently be higher while the applied voltage is higher, but the voltage will drop very quickly, and the resultant system energy will indeed remain the same.

  • @johnwrightoverlandingrobotics
    @johnwrightoverlandingrobotics 2 роки тому

    Voltage Doubler Ckt: 2(VAC * 1.414 - diode drop) = VDC
    Be careful not to confuse VAC with Vp as Vp = VAC * 1.414
    Capacitors charge to Vp less and diodes they may have in series in voltage multipliers.
    So if you have 10VAC, you will see approximately 28VDC on the output. If we assume silicon diodes are used and use .6V as the nominal voltage drop for each:
    2(10VAC * 1.414 - .6V) = 27.08VDC

  • @tracelandreth8704

    during the positive part of the cycle, why doesn't capacitor C1 discharge as current flows through it, through D2, and then charge C2? In the video you say that after the negative part of the cycle, C1 remains at 11.7 volts across it.

    Your tempo and the insertion of additional information is on point!
    Is there a way to use a jouel thief and instead of lighting a led light, it would charge a capacitor and depending on the inductive level you should - in my understanding - get around 100 volts out of an AA batery?
    I have almost zero experience into what i should be focused on, but perhaps you can take the challenge. At least an understanding of what is the most efficient potential riser... either with condensators with ac pumping, or dc to dc inductive pumpking. Perhaps its better to start with ac and multiply the voltage that way?

      In the first half cycle nothing special will happen C2=AC, in the second half cycle C1=AC, in the 3rd half cycle the magic happens, AC+C1 in séries will charge C2 with double the voltage. (This is all ignoring the voltage drop across the diodes )

  • @NHL_B
    @NHL_B 2 роки тому

    I have the impression that if we start with the positive half cycle it can't work as it is explained. So What happens to the first positive half cycle ? since diode D1 conducts on negative half cycle ??? In all videos I watched, we always start with AC's negative half cycle so C1 get charged on the right terminal and with the positive half we get Vin + Vc (C1 charged) so 2.Vin. But actually only with C1 and D1, if we start with the positive cycle, D1 is reverse biased so no current flows to C1 If I am right because it's like D1 acts like an open circuit. So it's like the behavior we are looking for only starts when we have the first negative cycle so C1 get charged etc...

    Something is not right with explanation about C2. As long as the capacitor is rated at the input voltage (AC). Then it doesn't need to be rated at the voltage after D2. Search for Cockcroft-Walton and also Cockcroft-Walton.
