the article describes braking resistance parameters calculating method through the definition of recuperated energy and average power returned to the DC link. Mathematical model of power stage, which consist of rectifier, power filter, inverter with sinusoidal PWM three-sectional permanent magnet synchronous machine motor and take into account parameters of the electric drive of the azimuth axis trajectory...
This article deals with the simulation of the power converter with voltage-source inverter and sine-filter. The repetitive control system was designed. The existing power converter has a control system which makes Fourier transform of the output voltage to inject these harmonics with opposite phase. The new proposed system based on repetitive controller which is much simpler and with smaller CPU load...
Energy efficiency of the process equipment is achieved by the use of modern energy-saving electric drives. One of the ways of development such systems is the use of induction motor electric drive with power factor correction (PFC). The article provides analysis of PFC, built on the boost voltage converter, develop of its control system and also functional model, made in Matlab Simulink.
