Methods: Mathematical computer modeling are used with regard main parameters converter. Results: The paper presents schemes differences reactive power compensation installations, nowadays on electrified sections railroads. calculation thermal installation Static Var Generat...

Low-power switched-mode power supply converters are used in applications where size and efficiency are critical. The buck converter size can be reduced by elimination of the bulky filter capacitor. The filtering function of this capacitor can be replaced by an output current ripple compensation circuit. The compensating circuit is applied, based on inductor current measurement and linear amplif...
