That make sense and also confirms my earlier suspicions.
I havn’t had the oppertunity to use GaN or SiC for anything yet so I’m not super well read on thier properties besides the obvious ones.
yea, been there a few times… (mostly someone elses design that needed a quick fix)
this makes alot more sense now. But stepping things up to an even higher voltage for a few percentages in gain feels bit awkward from many design aspects
At some point I’m sure we’ll have a hoard of different si+x doped alternatives that has thier range of individual benefits.
It has to do with the way PFCs work. It’s basically a boost converter that follows the voltage input waveform. As a boost converter, it needs to have an output voltage higher than the peak input voltage, which for a nominal 264Vac max is at least 400V. This makes sense because, if you want to use every section of an AC voltage wave, you have to boost the voltage. A topology that can step-up and step-down continuously will be less efficient and more complicated.
Introducing the MFG charger, which stands for Muted & Fast GaN charger, but you and I both know what it really stands for Feel free to drop me questions here or shoot a DM over at @esk8supplies on instagram, I’ll answer them to the best of my abilities
Pre-production batch is finished and tested, we are now ready for production. The size of the batch will increase depending on the interest gauged here. Founders Edition will receive a $69 USD discount over the regular $299 USD price, and will receive free shipping.
Supply is limited on batch one and even more limited on the Founders Edition units.
IP rating and UL certificate are pending, but the necessary tests in order to survive through these are done. The UN38.3 certificate is not for this charger specifically, but rather for the packaging and safety of my other project of battery packs, which was going to include this charger in the box for those who buys them together.
To add to this, this is an awesome form factor with an XT port and power input both flush with the edge, this looks like it’d be great to mount to a top box on a mountainboard.
Gonna add a bit to this: UL certificate and IP rating are the two most expensive certificates on this list, combined would cost north of 20 grand, so they are pending atm. They will be properly addressed as soon as this project gains enough profit to support them.
So it’s about the same as size and weight of my super heavy meanwhile HLG320 charger but twice as powerful. I use the Meanwell for is very clean and stable output as it’s better for the battrys health charge times and less heat in the cells during charge. Would be interesting to see how the quality of the DC power out put is as a comparison.
Seems as tho the Radium High Performance Battery Charger mentioned earlier during design stages. Is a direct competitor so let’s do a quick comparison at the most used settings of 12s (I personally don’t know of any use or demand for 13 or 14s charger a 10-12s would have a larger market as mentioned multiple times above, but presuming technical difficulties to achieve In design)

Your design goals was for a better, group ride, smaller lighter, fast charger. Do you think you achieved your design objectives? am I missing important part iv over looked and not consider.
