Power Capacitors (MKP and MKD) for AC Filtering

With the increasing importance of power quality, TDK is focusing on AC filtering solutions. They are available in different terminal configurations and electrical parameters. Thanks to their simple design (round winding in an aluminum can), these widely used components offer high reliability at the same time. The TDK portfolio features two basic AC filter capacitor designs: single-phase and three-phase capacitors. When AC capacitors are used as filters, they suppress harmonic distortions and reactive power problems, thus improving power quality and reliability.

Applications

A typical inverter would need AC capacitors for filtering of harmonic distortions and reactive power. Depending on the power electronic topology, single-phase or three- phase capacitors can be used in different terminal options (fast-on, screw and clamp terminals) according to the electrical and mechanical requirements. The appropriate film capacitors for input and output filters of inverter systems are AC Filter capacitors.
