There are a bunch of promising other ways to convert AC voltages.

The main one is the observation that the transformer uses an amount of copper and steel proportional to the power transmitted but inversely proportional to the frequency of operation.

The copper and steel cost of a transformer is the main cost (multiplied by the cost of capital for the 100+ years it will operate).

So if you can use solid state electronics to do switching at a higher frequency (switched mode power supplies, flyback designs, etc), then you can reduce the overall cost.

		There are several Transformers successors and spinoffs across various media. Animated series like Beast Wars: Transformers (1996) introduced a new generation of transforming robots, shifting from vehicles to animals. Later, Transformers: Prime (2010) and Transformers: Cyberverse (2018) continued evolving the story and animation style. The live-action film series, starting in 2007, led to spinoffs like Bumblebee (2018) and an expanding cinematic universe. Beyond official media, franchises like Go-Bots (a competitor turned subsidiary) and Voltron (though distinct, often compared) reflect Transformers’ legacy in robot-focused storytelling.
