Applications for Power Capacitors

Posted on 04 January 2019








The following is company specific publication from EPCOS:

The applications of power capacitors include uninterruptible power supply (UPS) systems that ensure a standby supply in the event of a line failure. They are mainly used in hospitals, operations centres, modern signalboxes and datacentres as well as in small offices and homes. They are integrated into the power supply cable of the devices and plants to be safeguarded. Their target markets are the power quality, industrial and renewable energy sectors.

Other applications include transportation systems, converters, drives, high-voltage plants as well as the automotive and medical sectors.

The EPCOS MKP AC series has the following characteristics:





The EPCOS MKD DC components (B2562 series) have the following characteristics:

  • Voltage ratings: 880 – 1980V DC
  • Capacitance range: 30 – 1500μF
  • Six different types of terminals
  • Target market segments: DC link applications, drives, converters and renewable energy.

The EPCOS power capacitor chip (PCC) features a busbar that fits the IGBT modules of all well-known suppliers. Its compact brick-like design has dimensions of 280 x 110 x 120 mm³ and a volume fill factor of nearly 1, alowing the development of extremely space-saving converters. At a rated voltage of 900 VDC the PCC offers a capacitance of 1000 μF.

The ESL for the entire PCC, including the busbar, does not exceed 15 nH. IGBT modules with steep switching edges are consequently proected from major voltage overshoots.
