In this talk, the main novelty is the “VA interpretation” of power conversion, that enables the calculation of the minimum required power to be processed in power converters. It is valid for 2-port converters tough it is especially enabling for n-port converters. This methodology also enables the synthesis of specific power topologies to operate in the fundamental limit of power processing.
Key applications are stacking of sources (PV cells), loads (data processing cores) or batteries. “Partial power” and “Differential Power Processing, DPP” architectures may also be assessed with the “VA area ” approach. Even more relevant is the case of energy buffered converters, as those required in single-phase inverters connected to domestic batteries/PV panels or those required in AC adapters and chargers with Power Factor Correction. The methodology is illustrated for the “Little Box Challenge” (Google and IEEE-PELS) specification and to supply 1000A to A.I. chips from 48V or 12V bus.
