| Abstract: | Based on the cascaded system stability criterion, this paper analyzes the impedance relation of converters in cascaded system, discusses the effect of LC filter circuit to load input impedance and the principle of improving stability of cascaded system, and introduces current source disturbance testing method for the measurement of cascaded system stability. Experiments verify the effect of LC filter circuit to the stability of electronic cascaded systems. |
