Hi everyone, I’m new to the forum so thank you in advance for any help or guidance.
My end goal: Power a 74vdc (67v min input, 15 amp max) 120vac (potentially 7 amps) output inverter.
My problem: I will often be using the standing voltage of Two 32 volt batteries in series. Standing voltage is often 60-66.
I have been able to find many step up converters that were 10-60 Vin (60 wouldn’t be high enough for the 61-66v I will commonly have) and 12-90 Vout. Theoretically, they’re up to 25 A at the 60 volt with a conversion efficiency of 92-97%. Which should get me around enough wattage to use around the maximum output potential of the end inverter. For what it’s worth, I will probably rarely ever draw around or more than 500 watts on the 120v output of the inverter.
Does anyone have any suggestions (preferably under $100) on how to take my standing voltage of (lower than 60 would be great but not necessary) at least 60-66 and get it to 67-74 (MAYBE as high as 80v at the very high end? Manufacturer didn’t provide much for specs, so I’m going to email them to figure out things like accepted voltage range.)
I have no problem building a step up converter if I were guided in the right direction. However, at my experience level with this side of electricity, I’ve greatly struggled trying to figure out the specs/values needed on the components. I’ve done my homework and it would seem that the easiest way is through using an inductor, a switch (transistor, pwm, maybe more options I’m unaware of), a diode and a capacitor. But frankly, I’m not smart enough just yet to figure out exactly what parts I need. Even when I look at the formulas, I’m not able to quite put the pieces together.
I also wouldn’t be opposed to dropping the voltage from 61-66 to around 55-60 so I could used the aforementioned step up converter. I just couldn’t find (or maybe figure out) a rheostat, pwm, variable resistor (that wasn’t huge, I’m a little limited on space) or anything along those lines that would work for my given needs.
I do understand the inherent danger of working with these components/levels of voltage and amperage. I will proceed with caution on any advice/guidance given and at my own risk. Thank you for reading, I’m young and I know I can be scatterbrained when it comes to explaining my ideas/situation. If you have any questions, ask away. Thanks!
