Development Of A Principal Diagram Of A High-Efficiency Coefficient Of A Frequency Inverter

Аннотация

The article developed frequency converters with increased efficiency for industrial enterprises. The principle of operation of existing methods and circuits of frequency converters has been studied and a schematic diagram of a highly efficient coefficient of a frequency converter has been developed. Analyzes switching currents in power switches of frequency converters, energy losses associated with switching, losses associated with output rectifiers, improves analysis of the main power consumption in a switching power supply, high-frequency variable frequency control system efficiency, high power dissipation and high timing diagram for automated systems explaining the principle of operation of frequency variables with a useful operating coefficient, a new block diagram of improved frequency variables were developed, the circuit was changed, and an increase in efficiency was achieved. KEYWORDS Frequency converters, rectifiers, switches, transformer, automation, thyristors.
