Abstract
A power circuit for N series connected loads according to the present invention includes N transformers having primary windings connected in series across a constant current AC source and secondary windings connected in series with the N loads. N-1 conductors are coupled from a junction between the loads to a corresponding junction between the secondary windings. Failure of one of the loads resulting in an open circuit will not interrupt power to the remaining loads.
