Pulsed Power Circuit Using Hybrid Energy Storage With Controllable Output Impedance

A circuit method for a pulsed power generator has been proposed and tested. It is based on hybrid energy storage (HES), which is a combination of capacitive energy storage (CES) and inductive energy storage (IES). By properly adjusting the energy ratio between the capacitor and the inductor, the circuit allows flexible control of the output impedance, while preventing harmful circuit response to unexpected load impedance variation. In addition, it allows energy recovery from the inductor after the output pulse. The proposed circuit has been intended as a module for more complicated pulsed power systems. For this reason, output voltage adding has been demonstrated using five stages.
