  • Patent number: 5737201
    Abstract: This invention relates to an electronic device for the conversion of electric energy between a voltage source E and a current source J. This device is comprised of cascaded switching cells (CL.sub.k) each having two switches (I.sub.Ak, I.sub.Bk) and comprising capacitors (C.sub.k) associated with the cells for distributing the voltage of the source over the switches, and control logics (LG.sub.k) which condition the exchanges of energy and are synchronized for limiting the voltage supported by each switch to a fraction (V/n) of the supply voltage, for limiting the ripple amplitude of the voltage of the output to the same fraction V/n and for conferring on this ripple voltage a frequency (nF) which is a multiple of the switching frequency (F) of the switches.

  • Patent number: 5716203
    Abstract: The invention relates to an injection device for burner heating apparatus provided with an air/gas mixture conduit including a Venturi element. This injection device comprises an injector holding tube (14), secured to a valve body (15) divided internally into two chambers by a membrane (23): an idle chamber (24) subjected to the pressure of the gas and communicating with the injector holding tube (14), and a compensation chamber (25) set to atmospheric pressure, enclosing a spring (27) able to urge the membrane (23) toward an idle mode state. This injection device comprises further a rod (31) secured to the membrane (23) and associated with idle mode stop means (34), said rod being extended by a tapered needle (33) arranged to traverse the injector (13) and determine with the latter a cross-section for the idle mode gas outlet, when the pressure of the gas is less than or equal to the idle mode pressure.
