There are on the

An isolation tranformer that is based on high frequency switching
electronics? Aren't isolation transformers basically 1:1 copper
windings on an iron core, potted in an epozy sand mix for thermal
mass?

Please point me to an example of an active electronics (lightweight)
marine isolation transformer.
