When was the SMPS power supply invented?

  1. Hello people.

    When was the first SMPS (switching) power supply invented?
    Was it invented when the color TV was created, the first computer was
    created [1], or what?

    [1] I don't know... the first computers used the linear power supply,
    and obvious that tube-based computers weren't using switch mode power


    Sorry for my bad english... :-/

  2. I read in sci.electronics.design that .:: Evanescence ::.
    Most of these techniques were invented 80 or more years ago. Certainly,
    the DC/DC converters for car radios, using vibrators, operated in
    'switch mode', and they were clearly a well-developed technique when
    introduced in the 1930s.

    Electromechanical rectifiers and inverters were in use in the days of
    Edison and also in rotating machines.

    The switches were switches.

    Operating principles were also used in RF transmitters and detectors.

    "Electrical Condensors" by Coursey, 1926, talks of HF welding and
    furnaces as if these techniques had been around quite a while then.

    Did anyone mention the automobile ignition being a flyback?

    Isn't it strange how the meaning of a simple word can change so
    drastically over a 50 year period.

    Actually in the late Victorian period there were vibrators advertised
    for medicinal purposes, the same way they advertised electromagnets.
    Ladies would go to doctors for vibrator treatments.

    Were they single, or just too slack ;-)
