Abstract (en)
[origin: EP1916877A1] Controlling the power supply of a magnetron comprises determining and memorizing a magnetron efficiency value, measuring the anodic current, measuring the applied voltage, calculating the difference between the target microwave power and the product of the anodic current, the applied voltage and the magnetron efficiency value, and modifying the microwave power as a function of the target power, the calculated difference and a predermined control rule. Independent claims are also included for: (1) device for controlling the power supply of a magnetron, comprising devices for performing the above operations; (2) installation for depositing a coating on a thermoplastic receptacle with the aid of a low-pressure plasma generated by excitation of a precursor gas with UHF radiation in a cylindrical vacuum cavity containing the receptacle, comprising a UHF generator and a UHF waveguide for connecting the generator to a window in the side wall of the cavity, where the UHF generator is a magnetron controlled as above.
