Abstract
Several storage condensers (1, 1′, . . . 1″) are mounted in parallel. Several thyristors (2, 2′, . . . 2″) are each mounted in parallel with one condenser (1, 1′, . . . 1″) to ensure the individual discharge of each condenser without modification of the condition of the other condensers. The discharge of the condensers (1, 1′, . . . 1″) is controlled in sequence so as to deliver to the secondary of the transformer a complex pulse comprised by a series of elemental pulses, each elemental pulse corresponding to the individual discharge of one condenser.

Closure electrifier with the transformer having a low mass magnetic circuit, comprising a transformer isolating the conductive element of the closure connected to the secondary of the transformer, a storage condenser for electrical energy and a thyristor adapted to be rendered conductive by a control signal applied to its trigger, to ensure the discharge of the storage condenser through the primary of the transformer and the delivery of a pulse to the secondary, characterized in that it comprises
- several storage condensers (1, 1′, . . . 1″) mounted in parallel,
- several thyristors (2, 2′, . . . 2″) each mounted in parallel to a condenser (1, 1′, . . . 1″) to ensure the individual discharge of each condenser without modification of the condition of the other condensers, and in that
- the discharge of the condensers (1, 1′, . . . 1″) is controlled in sequence so as to deliver to the secondary of the transformer a complex pulse comprised by a series of elemental pulses, each elemental pulse corresponding to the individual discharge of a condenser (1, 1′, . . . 1″), this individual discharge being controlled only when the magnetic circuit has returned to its initial condition.
