摘要

The invention describes an apparatus and a method for charging or discharging a piezoelectric element of a system, e.g., for a fuel injection system. The method and apparatus are characterized in that the current of a system is regulated as a function of a time characteristic and an event characteristic to achieve an effective low absolute average current.
