DESCRIPTION:The usual application scope of supercapacitors (SCs) is replaci
 ng electrochemical batteries\ndue to their higher power density and modera
 tely high energy density. In the current\ncomponent markets\, supercapacit
 ors are available with capacitances varying from 0.2 to\n7500 farads\, wit
 h the limitation of very low DC voltage ratings from 0.7 V to 4 V.\n\nThe 
 supercapacitor-assisted low dropout (SCALDO) regulator has been developed 
 as a non-\ntraditional supercapacitor application\, utilising the large ti
 me constant of SCs. SCALDO is a\nunique new design approach to developing 
 high-efficiency\, low-noise DC-DC converters\nbased on a linear regulator.
  During the past decade\, several implementation variations of\nSCALDO pro
 totypes\, including RS-SCALDO\, DO-SCALDO versions\, and an integrated cir
 cuit\ndesign have been achieved.\n\nThis lecture presents the essentials o
 f SCALDO theory\, several prototype implementations\,\nand a discussion on
  SCALDO properties. The success of the SCALDO projects led to the\ndevelop
 ment of the unique SCALoM theory\, in which the losses in the RC loop can 
 be\ntheoretically minimized by two combined steps: (i) adding a power elec
 tronics building block\ninto the RC loop\, and (ii) replacing the capacito
 r with a several-orders-larger SC.\n\nBased on this SCALoM concept\, curre
 nt ongoing research on supercapacitor-assisted (SCA)\npower converter circ
 uit topologies in Australia and New Zealand will also be discussed.\n\nSpe
