Isolated Power Using Capacitors


Abstract: An integrated H-bridge driver for isolated power-supply circuits (MAX256) usually drives the primary of a transformer,
but it can also drive a pair of capacitors that substitute for the transformer in providing isolation and power transfer.

A similar version of this article appeared in the June 15, 2007 issue of EE Times magazine.

Isolated power is usually generated with a transformer, but it can also be generated using capacitors. For some systems, the
constraints of size and cost may favor cap
