Discontinuous loads frequently compromise the performance of their power source and electronics. They cause the voltage and current ripple at the source and load, and introduce electromagnetic interferences. Also, they affect the efficiency of the power source. The aforementioned issues are particularly relevant in battery powered electronics. In order to minimise these unwanted effects, it is necessary to introduce a power supply architecture between the load and the source that should filter and/or regulate the currents and voltages. This architecture could be made solely of passive components or could use DC–DC regulators. The present work classifies and characterises the most relevant architectures available. A novel switched power supply architecture for pulsed loads with adaptive input current is also introduced. A mathematical analysis of the conditions and characteristics that the regulated architectures should fulfil to obtain the maximum performance in terms of efficiency and green electronics is provided. The simulation and experimental results shown in this study demonstrate the theoretical analysis.
