description: The object of the study is a 60 kVA lamp generator with a frequency of 1.76 MHz, which is used to power a high-frequency induction (HFI) plasma torch. A lamp generator is a converter of power frequency alternating current energy into high frequency current energy. This transformation is carried out using a generator lamp (triode) GU-66A and an oscillating system, switched on in a certain way. The generator lamp plays the role of a regulator, with the help of which the power supply of the oscillatory circuit is provided, as well as the maintenance of undamped electromagnetic oscillations in it. The presence of oscillations in the oscillatory circuit will cause the appearance of oscillatory power, which will be called the useful power of the generator. There are two main types of tube generators: with independent excitation and self-excitation. Their difference mainly lies in the fact that with independent excitation, oscillations are generated from the outside (from an external source), the frequency of these oscillations is set by the source. When self-excited, oscillations are generated inside the lamp generator and their frequency is set by the generator itself. In the process of performing the work, an approximate engineering calculation was made of the elements of the circuit of a lamp generator of two types: single-circuit and three-circuit, and their models were also compiled. In the process of performing the work, an approximate engineering calculation was made of the elements of the circuit of a lamp generator of two types: single-circuit and three-circuit, and their models were also compiled. The simulation was carried out in the MatLab Simulink software environment. In addition, a series of calculations of the lamp generator was carried out in various operating modes: independent excitation and self-excitation. As a result of modeling the lamp generator, it was possible to achieve a power sufficient to power the plasma torch. In general, during simulation, the system showed itself to be quite stable. All this suggests that the generator has successfully coped with the given load. The generator lamp used as a regulator of the oscillating circuit has demonstrated its effective operation.
