Nice idea, but my laptop won’t charge from power applied to a USB port. Next generation perhaps.

[right way right]

That scheming Bastard.

The new design allows for recycling power that in traditional designs is lost, preventing the loss of efficiency that typically occurs with other circuits when upping the frequency range.

Hmmm....

AC motored Hybrid Drivetrain Knuckle and use regen-braking back to a storage device with their Circuit?

How will this work with a "Graphene Ultra-Capacitor"?.... Wow a brave new world..

[Revolting cat!]

Revolutionary discovery of the month. Never to be heard from again.

If they go public, I’m buyin’ some of their stock.

I have designed switching power supplies for a living. I’d like to believe this, but like Johnny, I want to see the schematic. How are they charging/discharging the gate capacitance so quickly? Power FETs or IGBT’s usually have large gate capacitance. I want to see how they eliminate this or get around it. They’d have to if they are going to run the switcher at 300 MHz.

Very high frequency hmmm. VHF

Let me know when they use DHF

Others have addressed parts of this issue on this thread, but primarily I would like to see certain issues explained. Primarily though, is this truly a "circuit" using off-the-shelf components? If so, why has it not already been produced?

I can design and build equipment that works with quite standard components to about 987MHz rather non-expensively, but what else does it require? Inductance and capacitance at those frequencies AND above tend to be affected not only by the components themselves but also by the properties of the circuit boards they are manufactured on including the length and layout of the traces themselves.

Then, there is the matter of common-access materials. As an example, one of the components I used for a particular company some time back was a custom chip that had to be constructed in a particular way -and there was only one company that had access to the licensed technology to produce it.

Or, if it was a programmed chip, such as a one-of-eight-selected frequency divider (out of a possible 4096 combiniations) that had to be set at the factory (much like an FPGA), not everyone is going to be able to reproduce the circuit at home with even a simple EEPROM programmer and a soldering iron.

If that is the case, just how "reproducible" or "cost-effective" are we talking about here? Especially since you are at the mercy of one particular OEM if that is the case and who can tell when or what the pricing will change to in the future?

I am reminded of needing to obtain the proprietary Intersil chips some years ago if you wished to make a "cheap" Frequency Counter. Who was the only IC OEM licensed to manufacture them, so if you could not locate a source for their specific chips, you were not going to be building the design at all.

Sounds like he could make a mint on these things
