    Power Supply for capacitor bank

    Its supply is from either a 12V or 14.8V battery, I'm leaning towards the 14.8V.  The capacitor bank that the PS is supposed to charge is 2x 400V 470uF capacitors in parallel for 400V 940uF.  Am I misunderstanding, I thought the PS MOSFETs/IGBTs would need to match the capacitor voltage, do they...

    Power Supply for capacitor bank

    Is it better to use an overated component or should they match more closely?  (For example: My circuit will likely operate at 400V and 5-6A or so, should I use a 400V 5/6A MOSFET or IGBT, or would it be better to use say a 500V 10A model?)  I prefer to make things as efficient and durable as...

    Power Supply for capacitor bank

    What are peoples' feelings on IGBTs vs MOSFETs in SMPS applications? Also, I figure I can control device activation with a lower voltage/amperage switch in front of the battery, but what about the actual capacitor bank discharge control?  I'd like to be able to control it from a microcontroller...

    Power Supply for capacitor bank

      I'm finally beginning to isolate some of the specific components based on a shared schematic I found online slowly adapting it to my specific application.  As I figure it out, I plan to ask more specific questions in an effort to optimize the design for my application.    One question that...

    Power Supply for capacitor bank

    I see the 555 has 3 different modes.  Looks like this application calls for it to operate in the Astable mode.  Is the purpose of the oscillation to create a particular wave form or is it for pulse generation?  Also does it inherently create a given frequency in this mode?  One of the...

    Power Supply for capacitor bank

    Does it make any difference that they are two 400V 470uF capacitors in parallel?

    Power Supply for capacitor bank

    I see you are highly rated HERO.  In a supply for a 400V 970uF capacitor bank powered by either a 12V or 14.8V battery, is there a particular IC that you would recommend?  Also, what is the best way to determine what ratings of other components are needed.  I have already obtained a few low...

    Power Supply for capacitor bank

    Inductors vs Transformers I've heard both terms used.  Are they the same thing, different classes of something or simply a vernacular thing? 555 vs other power regulating ICs pro's and cons?

    Dual battery Dual charger board with IO monitor output

    The instructables website has a project that works on this premise.  I believe it was designed for 120vac, however the stepper/converter for that is relatively simple, I believe and fairly available.  Likely find that at instructables too.  Also, I believe I saw a video on youtube that combined...

    Power Supply for capacitor bank

    Phooey, had to redesign my project a bunch.  Still a lot I'd like to learn about the basics of power supplies, particularly operating off of a battery pack.  Can anybody suggest a good resource for learning/researching about these, or better still anyone with experience that can share?

    Power Supply for capacitor bank

    Hey pyro, thanks for the link.  It is interesting, and covers some points that I hadn't been able to find good info on so far.  Your bank has some hefty capacitance, what are you using it to drive?

    Power Supply for capacitor bank

    I have a capacitor bank of 6x 400V 470uF capacitors in series parallel (2 wide, 3 deep) that I'd like to charge from a LIPO battery pack (most likely 12-14 volts).  Can someone help me with the basics of designing a power supply?
