Yes, but when said transducers are used to perform work, as in the
conversion of one form of "power" to another, they are typically
called converters, generators, tractors, PTOs. All of these things
are rarely referred to as a type of transducer though technically they
fit the definition, and are transducers. It's just that the term is
usually used in metrology, and control systems and subsystems.
It's all just how things evolve in and through the industries.
DC to DC converters happen to convert one voltage of the same type
of energy to another voltage of the same type of energy. An AC
generator driven by a small internal combustion engine is called a
generator. Same thing for a huge turbine driven model.
