ENERGY SECTOR POWER ELECTRONIC CAPACITORS DC LINK CAPACITORS & SNUBBER CAPACITORS RELEVANT FOR WIND PLANTS, SOLAR POWER PLANTS, MEDICAL AND INDUSTRIAL EQUIPMENT, CAR ELECTRONICS AC/DC GENERAL PURPOSE CAPACITORS RELEVANT FOR POWER ELECTRONIC APPLICATIONS WITH HIGH CURRENT AND HARMONICS DISTORTION WITH LONG LIFE EXPECTANCY

CAPACITOR SELECTION GUIDE ISKRA MANUFACTURES AND SUPPLIES A WIDE RANGE OF POWER ELECTRONIC CAPACITORS WHICH CAN BE USED FOR VARIOUS FUNCTIONS IN ELECTRIC CIRCUITS. THEY ARE MOST COMMONLY USED IN FREQUENCY OR VOLTAGE INVERTERS, UNINTERRUPTIBLE POWER SUPPLIES, MOTOR DRIVES, WELDING EQUIPMENT, WIND AND SOLAR POWER SYSTEMS. A TYPICAL SWITCHING-MODE POWER SUPPLY IS SHOWN IN THE FIGURE BELOW. DC LINK CAPACITORS AT POSITION C1 ARE USED FOR DC VOLTAGE SMOOTHING. CAPACITORS AT POSITION C2 ARE SNUBBER CAPACITORS. WHEN A SWITCH OPENS, THEY ELIMINATE VOLTAGE SPIKES CAUSED BY CIRCUIT INDUCTANCE. AC...
