[C38] Listserve Digest, Vol 5, Issue 17

[Les]

Most of the small inverters are of the psuedo sine sort.  Switching
regulators (like the really small wall-warts) won't work with them at
all.  It has to do with the effect of having two on and off switches in
series and the inductor/capacitor of the switching regulator not having
sufficient intermittant duty cycle to handle the long zero voltage time,
so the voltage never really rises to the correct charge point.
