Abstract
Inductive energy from the coil of an electromagnetic actuator is stored in capacitive network at a relatively high voltage when the actuator is deenergized. When the actuator is energized, the capacitive network is coupled to the coil thereby releasing the stored energy at a high voltage to the coil.
