Single-capacitor electronic detonator and system for firing such single-capacitor electronic detonators

A single-capacitor electronic detonator, comprising:

• an explosive initiator (11), electronic controller (16), a single energy storage capacitor (15) connected to said electronic controller (16) and to said explosive initiator (11), and connection means (13) for connection to an energy source (12) for supplying said single energy storage capacitor (15) with energy, said single energy storage capacitor (15) being designed to supply said electronic controller (16) with energy and said explosive initiator (11) with energy when said single-capacitor electronic detonator (10) is fired, wherein the single-capacitor electronic detonator also comprises a clipper (18) for clipping the voltage across terminals of said single energy storage capacitor (15), said clipping means clipper (18) having a threshold clipping value (Us) lower than a non-firing voltage value (Ua) of said explosive initiator (11), said clipper (18) being controlled by said electronic controller (16) between an activated position, in which said clipper (18) limits said voltage to a value lower than said threshold clipping value (Us), and a deactivated position, in which said clipper (18) is inactive.
