Current Control Modulators: General Theory on Specific Designs

High power distribution in continuous or pulsed mode on board application satellites has drastically complicated the design of power conditioning regulators by requiring the reliable operation with brilliant dynamic behavior of complex modular structures to satisfy their powerful loads. Current control modulators satisfy these requirements by the energy control capability. The 50-percent duty ratio instability is analyzed for each power cell configuration and canonical small signal models are given and verified in the case of an MC2 buck regulator. The model validation is verified by application of the least square measurement technique which allows the accurate determination of any transmittance of the closed loop system.
