In this paper, a direct control of a flying capacitor inverter is proposed. This control allows to limit the number of commutations in a switching period with the use of a pre-calculated output voltage profile. A predictive control is made for the 3 phases 4 levels inverter in a active filtering operation. The advantages of this direct control is to reduce the switching frequency of the IGBTs, to...
This paper proposes a power converter for induction heating which can control the output frequency. This power converter is using a configuration named MERS (magnetic energy recovery switch). A 90 kVA 150-1000 Hz controllable frequency power supply for steel strip induction heating was developed. The power supply used optimally designed IGBTs for the MERS configuration. Loss reduction due to soft-switching...
The present research study is focused on the design, development and validation of a device based on multilevel converter for medium voltage distribution networks. It regulates the reactive power exchanged with the grid (up to 3 MVAR), allowing to achieve the following objectives: Network voltage regulation, reactive power compensation and power factor control. The device is composed by an IGBT based...
