On capacitor–less linear–assisted DC–DC regulators as candidate topology for photovoltaic solar facilities [PDF]

open access: yes, 2016
Linear-assisted DC/DC converters (or linear-switching hybrid DC/DC converters) consist of a voltage linear regulator (classic NPN or nMOS topologies and LDO) connected in parallel with a switching DC/DC converter.
