Abstract
A circuit for connecting lower AC voltage-rated AC-DC power supplies with higher voltage power sources. A power line matching transformer connecting the source to the power supplies needs only to support the self-dissipation and output current mismatch between supplies. The circuit can also protect the line matching transformer from overheating in various fault scenarios.
