Optimal design of a two-winding inductor bouncer circuit
(2009)2009 IEEE Pulsed Power ConferenceIn many pulsed power applications the flatness of the output pulse is an important characteristic to enable proper system operation, whereas a pulse flatness within less than a few percent has to be achieved. In power modulators based on capacitor discharge this voltage droop is mainly defined by the input capacitance. In order to overcome this problem, in power modulators systems, compensation circuits are added, whereby in spite of a ...Conference Paper -
Balancing circuit for a 5kV/50ns pulsed power switch based on SiC-JFET Super Cascode
(2009)2009 IEEE Pulsed Power ConferenceIn many pulse power applications there is a trend to modulators based on semiconductor technology. For these modulators high voltage and high current semiconductor switches are required in order to achieve a high pulsed power. Therefore, often high power IGBT modules or IGCT devices are used. Since these devices are based on bipolar technology the switching speed is limited and the switching losses are higher. In contrast to bipolar devices ...Conference Paper -
Transient behaviour of solid state modulators with Matrix Transformers
(2009)2009 IEEE Pulsed Power ConferenceSolid state modulators based on pulse transformer offer the advantage, that with the turns ratio of the transformer, the primary voltage ideally could be adapted to the available switch technology and a series connection of switches could be avoided. For increasing the power level several semiconductor switches must be connected in parallel and a balancing between the different switches must be guaranteed. There, the Matrix Transformer ...Conference Paper -

Dual-Inverter Topology for Single-Phase Supplied Drive Systems without Electrolytic Capacitor
(2021)2021 24TH INTERNATIONAL CONFERENCE ON ELECTRICAL MACHINES AND SYSTEMS (ICEMS 2021)Single-phase supplied variable speed drive (VSD) systems are widely used in industrial applications and typically feature a two-stage design with a power factor corrected (PFC) boost rectifier and a three-phase voltage source inverter (VSI). However, the electrolytic DC-link capacitor, which is needed to cope with the twice grid frequency power pulsation, and the required boost inductor are unfavourable in terms of reliability, volume, ...Conference Paper -
