This paper discusses a cost-effective technique for dynamic testing of DC-DC power supplies, based on the injection of a signal into the feedback loop of a DC-DC regulator, which makes it operating as a dynamic source or a dynamic load. The theoretical background and the practical implementation of the technique are investigated. Guidelines are provided to determine the static set-up and the bandwidth...
Supercapacitor assisted low dropout regulator (SCALDO) is a new approach to designing high-efficiency DC-DC converters by combining supercapacitors and a commercial LDO. In this approach, the end-to-end efficiency of the converter is increased by a multiplication factor, in the range of 1.33 to 3, compared with the efficiency of a linear regulator circuit with the same input-output voltages. SCALDO...
