Patent ID: 8089262

Claim:
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; said input voltage signal varying at a first frequency and having a first maximum amplitude; the apparatus comprising: (a) at least one signal transferring unit coupled with said input locus and with said output locus; and (b) at least one energy storing unit coupled with said at least one signal transferring unit; said at least one signal transferring unit including a plurality of switch units coupled for operation at a second frequency substantially equal with said first frequency to effect passing said input voltage signal to said output locus as said output voltage signal in at least one predetermined time interval of said output voltage signal; said output voltage signal having a second maximum amplitude less than said first maximum amplitude during said at least one predetermined time interval; said at least one signal transferring unit cooperating with said at least one energy storing unit to store energy in said at least one energy storing unit and to present energy from said at least one energy storing unit at said output locus as said desired output voltage signal when said input voltage signal is not passed to said output locus; said desired output voltage signal presenting a generally square wave representation of said input voltage signal; said desired output voltage signal substantially having said second maximum amplitude.
