The present invention relates to an overvoltage protection system for an electric aircraft to protect the aircraft electrical network from overvoltages that may occur during excess power regeneration by electrical propulsion engines. If excess regeneration power occurs in the network, which is detected by permanent voltage monitoring, the excess power is diverted in a controlled and regulated manner to dissipation devices for being transformed into heat. In order to maintain flight safety and dissipation efficiently, the dissipation devices are cooled down, preferably by means of an air flow to which the aircraft is subjected to during flight or by the propulsion air flow.
