Exciter circuit for aircraft ignition systems, has charging circuit with ferro-resonant transformer network having resonant frequency, and high voltage discharge circuit connected to energy storage device

摘要

The circuit (10) has a high voltage discharge circuit connected to an energy storage device and a charging circuit (32) that includes a ferro-resonant transformer network (34) having a coil with inductor (42) and capacitors (48,50) connected to its primary winding. The ferro-resonant transformer has a resonant frequency that is determined by inductance and capacitance values of the coil and the capacitor.
