Abstract :
Buck or boost single-inductor dual-input dual-output (SIDIDO) converters are popular in power-management and energy-harvesting applications. The fuel cell-Li-ion hybrid, unlike most applications discussed in literature, draws energy and power from a 0.6 V fuel cell and a 2.7-to-4.2 V Li-ion battery to supply a 1 V load and recharge the Li-ion battery, when unloaded, requiring a buck-boost charger-supply circuit. To this end, this paper describes and discusses the experimental results of the SIDIDO.
