Abstract

A power converter circuit (100) and a method of manufacturing the power converter circuit are provided. The power converter circuit comprises a plurality of electric modules (110) electrically connected in parallel. An electric module comprises a unique capacitor (111) and at least one switching device (112, 113) mounted at the capacitor. The power converter circuit further comprises a bypass switch adapted to allow a current to bypass the electric modules upon failure of at least one of the electric modules. In some embodiments, the switching device may be a transistor such as an insulated-gate bipolar transistor, IGBT, or a bi-mode insulated-gate transistor, BIGT. The power converter circuit may for example be employed in high voltage direct current, HVDC, power converters.
