In this paper, a five-level multilevel-clamped multilevel converter (5L-MLC 2 ) topology is analyzed based on a typical grid integration application for renewable energy system. The loss and thermal distributions of the power devices in different switching legs are investigated and illustrated under rated condition. Afterward, a loss and efficiency evaluation method is proposed and applied which takes into account various injected reactive power ranges regulated by the grid codes. It is concluded that the loss and thermal distributions of the 5L-MLC 2 multilevel topology are unequal between the clamping switching legs and the main switching legs; it also shows a good and consistent efficiency characteristic under different output power ranges when complying with the grid codes.

“…The switching energy losses depend on IGBT/diode current I C /I F and voltage V CE /V KA as well as stray inductance L σ of the IGBT/diode commutation path, IGBT gate resistance R G , and junction temperature T j [8] as given in (1) for turn-on loss. Besides, the conduction power losses depend on I C /I F and T j as given in (2) for IGBT.…”

Power electronic converters for wind turbines are characterized by high specific power density and high reliability. Special tests for such converters are performed in order to determine the power loss and thermal models, which are dependent of the load profile and converter structure. Two multi-level medium-voltage source converter topologies, of the 3L-ANPC-VSC and 3L-HB-VSC type, are considered in the paper. Both converters employ press-pack IGBT-diode pairs and interface a 6 MW wind turbine to a medium voltage grid. The power loss and thermal model data applicable for both grid and generator-side VSCs is used to estimate the switch junction temperatures through the simulation of wind turbine grid interface operation. A discussion of the power density and reliability of the grid-side VSCs with respect to press-pack switches, gate driver, and cooling plate is included. A test set-up for a single-phase full-scale 3L-ANPC-VSC being able to emulate both grid and generator-side VSCs is also described.

“…For diode dynamic test, the load inductance Lload position was switched to the lower pair of IGBTs. In this case (for extracting diode losses), the top pair of IGBTs behave as a DUT and bottom pair of IGBT modules goes in the passive mode (i.e., at VGE of -5.0 V and under turn off condition) [8]- [10]. The copper busbar connections from the DC-link capacitor to the DUT in the entire circuit give an approximate stray inductance of 100 nH.…”

In high power converter design, IGBT modules are often operated in parallel to reach high output currents. Evaluating the electrical and thermal behaviour of the paralleling IGBTs is crucial for the design and reliable operation of converter systems. This paper investigates the static and dynamic characterization of paralleling IGBTs and the influence of the electrical parameters on the IGBT behaviour. Si based IGBT power modules with voltage rating of 4.5kV and current rating of 1 kA are used for the experimental evaluation of module parallel connections. Parallel connected modules have been driven by several commercial IGBT gate units at various DC-link voltages and current levels and with different temperatures. The tested IGBT gate units show good current sharing performance between the two parallel modules. Other important influencing factors such as busbar design layout, stray inductance variation and gate driving are also investigated for parallel connections of IGBT modules. Finally, the switching energy of the paralleling modules is extracted for IGBTs and diodes under different conditions.
