Abstract
Projected cross point, a new current-mode control technique, is introduced and analyzed in this paper. Despite having an analog nature, the proposed method combines the advantages of both analog and digital control techniques. Unlike the conventional analog control methods, it accurately controls the average value of the inductor current with no need to a current compensator or an external ramp. In addition, while resembling the deadbeat characteristics of digital controllers, projected cross point control does not suffer from computational time delay, limit cycling, and quantization and truncation errors. Dynamic performance of the proposed approach is compared with the existing control methods. Analytical analysis and simulation results show the superior accuracy and transient response of projected cross point control approach.
