How much does it cost to switch, using semiconductors, an amount of electrical power?
IOW, how much does it cost to make a semiconductor switch per 1,000 watts? (Switching speed isn't critical, and some leakage is tolerable.)
Say it’s 100V DC, and you must switch on and off without an mechanical device. How much does it cost to make a semiconductor switch to handle 10 amps, in other words, a 1,000 watts at that voltage? How much does a semiconductor switch cost per 1,000 watts?
I'm envisioning a e-vehicle & roadway system, like a 3rd rail system, in which
The e-vehicles have a battery but normally are connected via 2 connector shoes to segmented strips in the pavement
The roadway has half-meter long conductor strips. One is the Ground and the other is hot, insulated from the surrounding ground but is still physically flat with the pavement.
When the vehicle is completely over a connector strip, it can be powered on. When the vehicle moves to expose a part of the hot strip, that section of the strip is powered off.
I'm trying to estimate the costs of the roadway of such a system.
