Abstract

This study examines an inverter converter as an element of the digital twin of the energy-technological subsystem of a bakery production line. Based on the structural design and the schematic electrical diagram, a structural–functional analysis of the device was carried out, the main energy conversion units were identified, and their role in ensuring the stable operation of the actuating mechanisms of the technological line was demonstrated. In the calculation mode, the PWM switching frequency is assumed to be 50 kHz, the equivalent primary voltage of the switching stage is ±20 V, the average rectified output voltage is 14.8–15.0 V, and the load current range is 0.1–3.0 A. Within the digital twin framework, the inverter unit is represented as an observable energy object for which the input voltage, load current, PWM signal duty cycle, switching frequency, and temperature of the power elements are taken into account. The output parameters include the output voltage, ripple amplitude, loss level, thermal state, and overload indicators. It is shown that when the load current increases from 0.1 A to 3.0 A, the output voltage decreases from 15.00 V to 14.15 V, while the maximum efficiency reaches 91.5% at a load of approximately 2.0 A. After applying an LC filter, the average output voltage changes from 15.2 V to 14.8 V, while the ripple amplitude decreases from 5.0 Vpp to 0.45 Vpp, i.e., by approximately 11 times, and the relative ripple is reduced from 33% to 3.0%.
