Abstract
The invention relates to a system (1) for controlling an electrolytic reaction in a reaction medium, with the system (1) comprising a primary energy storage (10), an intermediate storage (30) and a control unit (50). The control unit of the system is adapted for transferring electrical energy from the primary energy storage into the intermediate storage, monitoring the state of charge of the intermediate storage, establishing an electric connection between the reaction medium and the intermediate storage when the state of charge of the intermediate storage is larger than or equal to a first threshold value, and interrupting an electric connection between the reaction medium and the intermediate storage when the state of charge of the intermediate storage is smaller than or equal to a second threshold value. The invention further relates to an electrophoretic transdermal application system (40) comprising such a system (1) for controlling an electrolytic reaction for changing the pH value in the reaction medium of the matrix (43) of the electrophoretic transdermal application system (40), as well as to a method for transferring electric charges.
