Abstract
Relevance Oil production, storage, transportation and refining often require accompanying heating processes with careful control of input and output parameters. The most effective heating technology in oil production, refining and pipeline transportation complexes is induction heating. The specifics of oil heat treatment involve maintaining a certain temperature regime, which reduces its viscosity to the required level, while preventing coking. Induction heating technology allows regulating the output power, and therefore the heating temperature, in wide ranges (1–100 %), which allows maintaining a given temperature regime of action on oil. The use of a resonant mode for induction heating systems is energetically efficient. One of the methods for regulating the power of resonant systems is densepulse modulation, which ensures the maintenance of a resonant mode and a wide range of system regulation. Aim of research Develop an algorithm for the operation of a modulator that allows reducing the amount of memory occupied on the microcontroller and controlling the heating power of an induction heating unit. Research methods The following methods were used in this study: mathematical modeling, principles of signal modulation, computer modeling of the operation of a pulse-dense modulator. Results A dense-pulse modulation circuit has been created on the AVR microcontroller ATmega328, as well as a program code for the dense-pulse modulator circuit.
