<p>A process for eliminating the disturbances related to fluctuations of the load in chopped power supplies. A magnetic circuit with a primary inductance (Lp) is coupled to a secondary inductance (Ls). The value of the secondary inductance (Ls) is automatically adapted as a function of the voltage (Us) at the terminals of the load (X). This ensures total transfer of the magnetic energy for each period of the chopping frequency. Complete demagnetisation of the circuit is obtained at each period of the chopping frequency. This eliminates certain disadvantages in the prior art notably saturation of the circuit material which, in the prior art, results in incapacity to translate linear flux variation, causing a large increase in current in the chopping equipment, usually transistors, and thus the possibility of damage. 11</p> |
