TO THE QUESTION OF THE MAIN PERFORMANCE CRITERIA CALCULATION FOR ELECTRIC POWER STATIC CONVERTERS
Description
Widespread in autonomous systems, including uninterrupted power supply systems, there are power static (electronic) convertors: rectifiers and inverters, used to match the parameters of the electric power source and the load; they also have a function of voltage stabilizers. Important question is the calculation of key performance criteria at the design stage: power losses, efficiency, reliability, weight and size (for electrical transport systems). The article discusses the methodology of the simplified calculation of the basic criteria of efficiency of inverters and rectifiers. There are schematic electrical diagrams of power rectifiers and inverters, and the basic analytical expression for a simplified calculation of the basic criteria of efficiency of the converters, including their output filters. Each year, we improve the technical characteristics of the probes using new element base, allowing reducing the level of electromagnetic interference generated by power electronic devices. We have also shown perspective directions of the development of power converter technology by using one-phase and threephase transformers with rotating magnetic field in their creation (therefore we increase reliability of operation and efficiency). A promising direction is the construction of converters and autonomous systems in a modular complex, where (in addition to increased system reliability) we simplify its operation, including service
