Abstract: The present invention relates to a power amplification device capable of being powered by a single input voltage and comprising a switching module comprising a first discharge electrode and a second discharge electrode. The power amplification device comprises a triggering module configured to convert the input voltage into a first supply voltage and a second supply voltage, detect an activation event, generate an activation signal from the first supply voltage when an activation event has been detected, generate a pulse command from the second supply voltage when an activation signal has been generated, and transmit the generated pulse control to the triggering means of the switching module so that it triggers the formation of an electric arc between the first discharge electrode and the second discharge electrode.
