Computer Simulation as a Mean of Problems Addressing in Systematic Design of Electrotechnical Complexes

Abstract

Using the example of the problem of deep modernization of a commercially available three-phase voltage source inverter (VSI) for a special purpose backup power system, the results of its solution are given. As a means of solution, computer simulation (CS) is used. To achieve specified quality indicators, the system approach to design and modern principles of structural and algorithmic optimization of VSI are used as the methodological basis. In particular, a high-frequency two-channel push-pull step-up DC/DC converter (SUDCC) with a patented energy-saving snubber and an energy-efficient strategy of the pulse-width modulation (PWM) in the VSI are used. For reasons of improving reliability and improving the energy and mass-dimensions, VSI is also performed on a two-channel structure. With the same considerations, the function of regulation (stabilization) of the output voltage is assigned to the converter. The SUDCC is also partly involved in improving the spectral composition of the output voltage. Estimates are given for the mass-size and energy parameters of the synthesized device.
