Abstract:
An electrical coupling circuit for charging a load, such as a pulse forming network or capacitor load, to a precise voltage level, the coupling circuit comprising:an energy source; a transformer having an input winding connected to receive input power from the energy source; a switch circuit capable of selectively assuming a substantially open state or a substantially closed state, wherein the open state substantially prevents input power from passing from the energy source to the input winding of the transformer; an inductive charging circuit connected between an output winding of the transformer and the load; and a control circuit that causes the switch circuit to assume the substantially open state for a predetermined amount of time when the sum of the magnitude of the energy stored in the load and in the inductive charging circuit is substantially equal to a predetermined value, thereby allowing energy stored in the inductive charging circuit to be transferred to the load.
