  • ABSTRACT: The dc-link current in pulsed power inverters has in addition to the dc-value a substantially ac- component. This current heads up the dc-link capacitors and must be considered for the inverter dimensioning. Because these capacitors have a major impact on the volume, weight and costs of inverters the current must be exactly determinates. In this paper the rms-current in the dc-link capacitor is calculated depending on the phase output current amplitude, phase shift angle and inverter modulation factor. The calculations are verified by practical measurements.
