Latest Patents

One of Kittilä's latest patents is a power converter arrangement that includes an attenuation element for electrical ringing. This invention features a semiconductor switch system with a controllable switch and a capacitor unit that is operatively connected to the switch system. The arrangement also includes a conductor that conducts electric current between the capacitor unit and the semiconductor switch system. A resonant circuit is formed by the resistance, inductance, and capacitance, and the power converter arrangement incorporates at least one attenuating element that is conductively isolated from the resonant circuit. This attenuating element, made of ferromagnetic material, is magnetically coupled to the conductor, allowing variations in electric current intensity to induce eddy currents within it.

Another significant invention by Kittilä is a choke that comprises a magnetic core forming a closed loop. The choke features a coil wound around the magnetic core, with a cross-section that varies along the length of the coil. Each turn of the coil has an inner and outer portion, with the outer portion being wider and located further from the choke axis than the inner portion. This innovative design enhances the choke's performance in electrical applications.
