Hi Guys
A local company here has just released a series of high- powered Amps. Class D and powered by SMPS.
Light and wonderful and all.
I don't have faith in the SMPS part.
I can see failures of note. Besides trying to quell noise injecting itself back into the Amp...I loathe SMPS.
Unpredictable, canno't take a sustained 20 second Voltage overload from the Grid....because the Main Smoothing cap will burst.
And then the circuitry it powers will be compromised. Because the whole thing is unstable. If it even works anymore.....
But and I mean BUT: There are companies like Delta Electronics who employ Engineers who design SMPS
thoroughly. Sealed enclosure.....dissipating around 90W continiously.....for almost Six years now. Like my Lappie. Many times I have wondered when all other stuff fails around me with surges etc, this Lappie PSU has never failed
I take my hat off to Delta Electronics Engineers.
Proper SMPS design is a dark art.
Not like the TV SMPS I have to fix daily here.
