Methods for enhancing transient speed have been evolved around the reduction of effective inductance of the switching regulator through interleaving and paralleling converters. This paper introduces the concept of \"phantom load\" for achieving very fast and tight output voltage regulation for any switching converter. Essentially a special load corrector circuit is attached to the output of the switching regulator. This load corrector combines with the actual load (e.g., CPU chip) to form a slowly varying composite load or \"phantom load\" which permits the switching regulator to maintain a well regulated output voltage even when the actual load is changing very rapidly. This paper discusses the conceptual construction of the load corrector and its practical implementations. Experimental tests (based on available IC and discrete components) for a 20 A step load showing an output voltage fluctuation of less than /spl plusmn/30 mV are presented.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference.

Indeed, low supply current harmonic distortion and displacement power factor control including unity displacement power factor operation, can be obtained. However, the models of the CSRs and VSRs are nonlinear, which involves their analysis and certainly their control. This complexity is somehow avoided when using direct line current control and relatively high switching frequencies (>1 kHz). Unfortunately, this approach does not guarantees the stability of the rectifier, results in a dynamic that is load dependant and covers low to medium power level applications. This paper proposes the application of a nonlinear control strategy in combination with a high performance low switching frequency space vector modulation technique. The approach can be used in high power applications and allows the independent control of the two supply current components (active and reactive), which admits the converter to either generate or absorb reactive power according to a given set point while operates as an independent DC power supply. The paper includes a complete formulation of the system equations and a controller design procedure. Simulated results confirm the validity of theoretical considerations.","PeriodicalId":292317,"journal":{"name":"30th Annual IEEE Power Electronics Specialists Conference. Record. (Cat.
