    Help with saturable core switches

    I am wondering if anyone has had some experience with saturable core switches or magnetic pulse compression systems for high power pulses. I am trying to use the saturable core switch instead of a spark gap for high power pulses. I have been able to find some information on saturable core...

    Help designing a dual H-Bridge controller

    GS3, That seems to be a brilliant yet simple solution to the problem of shoot through. I was not familiar with this method. Do you happen to know an easy method to determine what is the appropriate inductance to use but also not really interfere with the maximum power available to the H bridge...

    Help designing a dual H-Bridge controller

    Once again, thanks for taking the time to give me some guidance on the best way to tackle this problem. Unfortunately, I think it will take me quite a while to learn how to use a microcontroller (I dont even know any computer languages). I will continue to study the ideas that you guys have...

    Help designing a dual H-Bridge controller

    Thanks for the response. I am performing an experiment on magnetic field interaction. I need the first B field to be at full north while the second B field is at neutral.

    Help designing a dual H-Bridge controller

    How do I ensure that the 3524s stay 90 degrees out of phase?

    Help designing a dual H-Bridge controller

    I am trying to build a circuit to control 2 H-bridges. The H-bridges outputs must be 90 degrees out of phase with each other. I was thinking about using a sg3524 signal to control one H-Bridge and using the same signal as an input to 2 556 timers acting as a delay and trigger signal to the other...

    Question about magnetic field interaction

    Thank you for your answer electricpete.

    Question about magnetic field interaction

    Suppose I had two air core electromagnets wound in a bucking configuration (ie North poles opposing each other) and they are also tightly coupled. Also assume it is 12 volts pushing the current through both electromagnets. If I was to terminate the current to one of the electromagnets very...

    Question about crossed magnetic fields

    Logbook, Thank you for the information about there being no interaction in air. That was going to be a future experiment which you saved me the time of trying. Skogsgurra is correct that I do need a bit of spoon feeding, but I do appreciate the more indepth explanation in addition to the...

    Question about crossed magnetic fields

    Skogsgurra, Thank you again for answering so quickly. Do you know a good source where I can read more on the vector addition rule or principle?

    Question about crossed magnetic fields

    I am not very familiar with magnetic design so please bear with my laymans terms. I am preparing to do an experiment on crossed magnetic fields. I am attempting to see what kind of interaction perpendicular magnetic fields have on one another. For this experiment I am planning on having a 1 inch...

    Series resonant circuit help

    P.S. I have been reading that Tesla did a lot of work on resonant circuits so I will study some of his writings.

    Series resonant circuit help

    Skogsgurra, Thank you for taking the time to write that explanation. It helped clarify some more things to me. I guess my big problem is that I wanted to understand how resonance occurs with a waveform resembling pulsating DC or such. As I stated before I am not an electrical engineer. My...

    Series resonant circuit help

    Like I said before I didn't mean to open a can of worms. I was just hoping to get a deeper understanding of series resonance which went into the precise interactions between the capacitor in inductor. Of course I can pass a test on what it is and the math problems concerning it. I just wanted to...

    Series resonant circuit help

    Skogsgurra, I am terribly sorry for wasting your time. I would not have posted if I had known that my question would upset some members. I am not an electrical engineer, I just really love electronics and talking about it. Once again sorry.

    Series resonant circuit help

    dpc, Thanks for the suggestion. I happen to have the 2006 version of the arrl handbook. I must not have looked close enough for a good explanation. Thanks again to taking the time to respond.

    Series resonant circuit help

    logbook, That maybe the direction I need to explore next. thanks

    Series resonant circuit help

    geekee, Thanks for your response. I have read that explanation before the the cap and inductor work together to bring current and voltage into phase. I may be on a pointless quest. I was just hoping to learn more deeply what happens in that small instant of time when current flow though the...

    Series resonant circuit help

    dpc, I am not really clear on the difference between the two definitions. I have played around with parallel resonant circuits and was able to drive them with pulsating dc at the resonant frequency. My example about was based on the calculated time constant for current to rise to maximum...

    Series resonant circuit help

    I am sorry about a miscalculation I did in the above post. In the first inductor example it would take current 1.665 seconds to rise to 4 amps.
