Folks,

The evolution of DC-AC inverter technology over the years has left many of us dazed and confused. The attached article from Trace Engineering (circa 2000) describes each topology along with their advantages and disadvantages. Amazing that after 23 years the venerable Trace SW series still competes well with the latest offerings from Magnum, Outback, Victron and the others in the mobile market. In fact, the only inverter that really competes with the SW in terms of surge capability, total harmonic distortion, idle power consumption, voltage regulation, and efficiency is the Hybrid style inverter, such as Magnum's MSH4024M. The only real relative disadvantage of the Trace SW technology is cost to produce.

Sooner or later The old Trace inverters will not be available thus those of us who have them in our coaches will be going to the Magnums, Outback's and others for replacement.
I and hope not too soon for me.

That's true Hish, but it's such a rugged design it really deserves to have some enterprising individual make replacement parts for it. From what I hear there's only a dozen or so NOS power boards and control boards in existence. I want to make sure that these inverters live long into the future.
