  PREFACE
  Switching Power Converter: an Early Example
  Although the origin of switching power converters is lost
  in antiquity, some early machines have been identified that
  work on this principle. Among the first was the hydraulic
  impulse pump, in use centuries before the use of electricity (see Figure 1). This device allows some of the energy
  in the stream of water flowing from point A to point B to be
  diverted to pump a smaller amount of water from point B
  to point C. Here is how this “water hammer” works (refer …
