The computer simulation is a powerful tool for assessment of the SVM (Space-Vector-Modulation) strategy and inverter. The methods to building the simulation model for them are analyzed, and a new modeling method is proposed and discussed. The new method models the SVM and inverter as a whole based on the start point of the SVM. The method to computing the DC link current is given based on the three-phase...
In this paper, a multi output high frequency soft switching inverter topology is presented for home use IH cooking appliances. The proposed inverter system is comprised of simple power circuitry and unique control scheme. The detailed analysis shows that the proposed inverter has low harmonic distortion, low switching losses and wide output power range. A detailed PWM procedure is illustrated as well...
This paper presents the practical implementation of three-level inverter using dual two-level inverter. A space vector PWM technique (SVPWM) is developed based on the combination of space vector from dual inverter feeding open end winding induction motor (OEWIM). A total of ??64?? combinations produce ??19?? operating vectors which make a hexagon shape similar to that produced by neutral point clamped...
A nonlinear load is a factor which effects inverterpsilas output voltage waveform in single-phase inverter system. Considering nonlinear characteristic, the load with uncontrollable single-phase rectifier with capacitor filter was modeled. The nonlinear model of the inverter system was obtained based on that. The model was tested to be correct through simulation analysis. Fuzzy control was applied...
