Design of a AC Current Source for Inductive Loads
Kui Hong Hao, Bin Li · Applied Mechanics and Materials · 2013
Inductive loads are common in the real time monitoring system of aircraft engines. The excitation for these loads is better to chose current source. A stored program control interchange current resource based on DDS and current feedback amplifier was designed for these loads. When the output frequency of the resource was chosen 5kHz, the export current can reach 10mA and the change of the amplitude is less than 1%.
