I would be more concerned about me smashing into a tree at 40mph than the bike. 40mph is an exaggeration, isn't it?

What an interesting and unique approach to online discourse! In general terms (not asking to reveal the secret sauce), how do you define the opinion groups? Latent Semantic Analysis?

The output of a solar array is a DC voltage (constant over time). Our homes are fed by an AC voltage (varying sinusoidally over time at a frequency of 60Hz). A circuit is needed to convert the DC to AC. There is a loss in energy due to the

FINsix solved a AC-DC power converter problem. This is a DC to AC inverter problem.

There are all sorts of specifications/requirements listed (box size, ripple allowed, EMI limits) but the most interesting that is not mentioned is cost. There is no upper limit set on the BOM cost.

You still need DC-DC conversion. High voltage DC transmission is already used in some parts of the world [1] [1] http://en.wikipedia.org/wiki/High-voltage_direct_current

Some solutions to the problem will utilize a high frequency, high voltage switching inverter. The performance of this type of inverter is limited by the losses generated by the devices making up the inverter. The wide bandgap devices (switc

Yep, Permanent Magnet AC (PMAC) motors are common types of synchronous motors. They are generally more compact than induction motors for the same power output. Induction motors are generally less expensive. An official (not forum post) arti
