Abstract:
A method of controlling a double-resonance generator delivering a direct-current output voltage supplying a load, in which an output current circulates, involving a delay time control of the transistors of the thyratron inverter of the generator, wherein the control involves a static term and a corrective term, a first table is elaborated, containing for predetermined couples of output voltage and output current values the corresponding values for the static term, and a second table containing corresponding desired values for a first voltage at the terminals of the resonant circuit capacitor and for the current crossing the inductance coil connected in parallel on the capacitor, as well as corresponding gain values a current sampling time the control calculated at the preceding sampling time is applied, and the control intended to be applied at the following sampling time is determined, the static term of the following control is determined from the first table and from the voltage and output current values estimated at the following sampling time, and the corrective term of the following control is determined from the second table, from the values determined at the current sampling time, from the output voltage and output current, from the first voltage and from the said inductance current, as well as from the value of the corrective term calculated at the preceding sampling time.
