Our solutions for power converters help to improve conversion efficiency, minimize power loss, and lower energy costs. Leading companies around the world trust KEMET products for efficient and reliable power conversion.
Power conversion has a significant impact on a wide range of industries including medical, commercial, and industrial. With power conversion comes the risk of power loss and a host of other complications, which is why securing the right products to properly convert power is crucial in any application. KEMET products provide optimal power conversion in industrial equipment, consumer electronics, medical devices, and more. Many power converters use a film DC-link capacitor in an AC/AC topology as an intermediary DC step between AC sections of circuits such as motor drivers and inverters.

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 in the harsh environment application
- Current sensors designed to monitor and control circuit switching archetypes
- Aluminum electrolytic capacitors offer excellent ripple current carrying capability with extended life for energy and power
Wide Bandgap Devices
Wide bandgap semiconductors, hailed as the next generation of energy-efficient materials, allow devices to operate at significantly higher voltage levels and frequencies than conventional materials. KEMET offers a wide range of components for wide bandgap devices to achieve greater power efficiencies.
- Capacitor resonant frequency can be found on our K-SIM tool to ensure it is performing below the higher switching frequency from wide bandgap semiconductors
- Increase power density with polymer’s high volumetric CV storage
- Class 1 dielectrics can deliver better efficiency with low ESR and consistent capacitance across temperature
- High temperature and low ESL film capacitors meet the high frequency requirements in resonant tank circuit and DC Link applications
- Tantalum polymer capacitors high volummetric efficiency and low ESR also make them suitable in Wide Band Gap applications where space is strictly constrained.
