  • Compact and lightweight power converter for high power comsumption loads
    Patent number: 8089262
    Abstract: An apparatus for shaping a varying input voltage signal received at an input locus to effect a desired varying output voltage signal at an output locus includes: (a) at least one energy transferring unit coupled with the input locus and with the output locus; and (b) at least one energy storing unit coupled with the at least one energy transferring unit. The at least one energy transferring unit presents at least one predetermined range of the input voltage signal at the output locus. The at least one energy transferring unit cooperates with the at least one energy storing unit to store energy in the at least one energy storing unit and to present energy from the at least one energy storing unit at the output locus when the input voltage signal is not presented at the output locus.
