Direct Drive Amplifiers & Voltage Converters - What is it?

DragonPetter · May 29, 2011

When talking about amplifiers or voltage converters, what is meant by direct drive? The only idea I have is that it does not involve a transformer.

Can anyone shed some light on the term "direct drive"?

I see it for example here:

near the bottom

"As the power amplifier is a direct drive, transformerless design, transducer tuning is usally not necessary. "

What is direct drive and how is it done? When I search google, I mostly come across the mechanical description of this, rather than an electronics description.
