Apparatus and method for controlling DC power to primary and secondary load utilizing capacitor

摘要

An apparatus for supplying and controlling electrical power having a power source for supplying electrical power to a primary load and a secondary load, a capacitor connected to an input to the secondary load and control means operable to cause an operating condition of the apparatus to temporarily change from, a operating condition in which power from the power source is supplied to the primary and secondary loads to an alternative operating condition in which power from the power source is supplied to the primary load but is supplied to the secondary load thereby increasing the minimum voltage the capacitor can maintain at the input to the secondary load.
