Abstract
Abstract A dual energy circuit for selectively generating high or low energy electrical pulses for supplying a spark gap or other load. The circuit employs a source of power comprising a power transformer and voltage doubling means to charge condensers of different capacities, and switching from one energy system to the other is effected in the high energy condenser charging path at low current.
