A '''vector inversion generator''' ('''VIG''') is an electric pulse compression and voltage multiplication device, allowing shaping a slower, lower voltage pulse to a narrower, higher-voltage one.

VIGs are used in military technology, e.g. some [[directed-energy weapon]]s, as a secondary stage of another pulsed power source, commonly an [[explosion explosive-driven ferroelectric generator]].

A spiral VIG consists of four alternating conductor-insulator-conductor-insulator sheets, wound into a cylinder, forming a [[capacitor]] also acting as a single-ended [[transmission line]], connected to a [[spark gap]] switch. The capacitor is charged from a power source, e.g. the EDFEG, then the spark gap fires after its [[breakownbreakdown voltage]] is reached. The [[electromagnetic wave]] created by the spark discharge travels along the transmission line, converting [[electrostatic field]] to [[electromagnetic field]], then after reflecting from the open end converts back to electrostatic field. A pulse of output amplitude 2nU (where n is the number of turns of the capacitor and U is the initial voltage it was charged to) and a rise time equal to twice the [[electrical length (transmission medium)|electrical length]] of the transmission line.[http://scholarsmine.mst.edu/post_prints/pdf/physics_09007dcc80588630.pdf]

[[Ferrite (magnet)|Ferrite]]s can be attached to the VIG construction to modify its characteristics.[http://www.findthatpatent.com/Apparatus_and_method_for_generating_high_voltages_using_a_voltage,7151330.html]
