Abstract
Regulated charging of an energy storage module in a pyrotechnic device such as a firing capacitor in an electronic detonator, preferably in the form of constant-current charging limited at a 'rail voltage,' and optionally limited to a sufficiently low current to provide additional benefits to the pyrotechnic device such as in the case of a short-circuit.
