Power Converters

Power Converters

Power converters are solid-state or electromechanical devices used to convert electrical energy from one form into another. DC-link, resonant converters, and switched-mode power supplies (SMPS) perform reliable AC to DC, DC to AC, DC to DC, and AC to AC conversion. KEMET’s power electronics can improve conversion efficiency, save energy costs, and minimize power loss. 

Our components enable power conversion in a wide range of devices, including: 

  • Variable Speed Drives (VSDs)
  • Uninterruptible Power Supply (UPS)
  • Inverters

Low Parasitic Devices

Low Parasitic Devices

Parasitics are unavoidable qualities created by the construction of a capacitor or an inductor. The leads on a capacitor create unwanted inductance and the parallel wires can increase undesired capacitance. These small parasitic qualities can add up and disturb sensitive power conversion circuits and digital equipment, such as in automotive body electronics which allow users to access and control safety features including ADAS and power systems.

  • Parasitic models of capacitors can be found on K-SIM, so you can design in our parts with confidence
  • Extremely low parasitic parts are available, such as the low loss orientation of our U2J KONNEKT, which lowers ESR and ESL by changing the way the capacitor is mounted

Power converters are ubiquitous devices that play a role in applications such as inverters for solar panels, drive systems, electric vehicle (EV) charging stations, and much more. These devices convert electrical energy from AC to DC or vice versa in electronic equipment, board-level power conversion, and electric power supplies. 

  • METCOM inductors are designed to be a drop-in replacement for existing designs with values commonly used in switching mode power supplies
  • Polymer capacitors can give you the most CV out of your capacitor when space is an issue
  • Ceramic capacitors, like KONNEKT, can give you the low ESR needed to design highly efficient LLC or resonant tank converters
  • AC and DC chokes, EMI cores, and ferrite beads can help when there is trouble with EMC
  • Film capacitor technology supplies the high energy and high reliability needed on the harsh environment application
