Accurate thermal dynamics modeling of high power Insulated Gate Bipolar Transistor (IGBT) modules is important information for the reliability analysis and thermal design of power electronic systems. However, the existing thermal models have their limits to correctly predict these complicated thermal behaviors in the IGBTs. In this paper, a new three-dimensional (3D) lumped thermal model is proposed, which can easily be characterized from Finite Element Methods (FEM) based simulation and acquire the thermal distribution in critical points. Meanwhile the boundary conditions including the cooling system and power losses are modeled in the 3D thermal model, which can be adapted to different real field applications of power electronic converters. The accuracy of the proposed thermal model is verified by experimental results.

Recently, a hybrid modular multilevel converter with cascaded full bridges (HMMC-CFB) is proposed. This converter has mainly two parts: a director part (DP) and a wave shaping part (WSP). The DP consists of a conventional modular multilevel converter (MMC) with half bridge submodules (HBS). The WSP is a series connection of full bridge submodules (FBS) and attenuates the voltage harmonics produced by DP. The energy exchanged by WSP changes with modulation index and causes improper capacitor voltage regulation. For satisfactory operation of HMMC-CFB, the total capacitor voltage of WSP should remain constant. This paper presents an analysis of energy exchanged by WSP and proposes a new control technique to regulate the total dc voltage of WSP. In the proposed control, the energy exchanged by WSP is controlled by changing the slope of the voltage reference signal of DP. In addition, analysis of circulating current of HMMC-CFB is presented. A circulating current suppressing controller (CCSC) is used to control the second harmonic component. The performance of the proposed control technique for the standalone model of HMMC-CFB is evaluated by using time domain simulation studies in the PSCAD software environment. To test fault blocking capability of converter, a grid connected model is built in PSCAD and analyzed for dc fault tolerant capability.

An improved bidirectional medium voltage AC-DC converter based on 10kV silicon carbide (SiC) MOSFETs for SST (Solid State Transformer) application is presented in this paper. Avalanche breakdown of the reverse blocking silicon diode and bridge arm shoot-through problems in traditional high voltage bridge-type AC-DC converters are solved. Shoot-through currents are limited to low di/dt events that are readily controlled, allowing zero dead-time operation. The reverse recovery dissipation of the SiC MOSFET is eliminated because no freewheeling current will flow through the body diode. This increases the efficiency as well as the reliability of the SiC MOSFET. Detailed power stage operating principles and energy transfer mechanism are described. A unique customized 10kV SiC MOSFET/JBS diode power module is developed and tested, which further reduces parasitic parameters and simplifies converter wire connection. This topology is therefore a very good choice for median voltage applications.

This paper presents a soft-switched discontinuous pulse-width pulse-density modulation (PWPDM) scheme to decrease the switching losses of the capacitor-less high-frequency pulsating dc-link (HFPDCL) inverters. The proposed modulation scheme employs both pulse-width modulation (PWM) and pulse-density modulation (PDM) schemes to increase the overall efficiency of the inverter and generate high-quality output line-frequency (LF) Sine waveforms. In order to increase the efficiency of the converter, it decreases the switching requirement of the converter and it also provides soft-switching condition for the output inverter. The performance of the proposed PWPDM scheme is verified using am experimental 2 kW HFPDCL inverter.

In this article, a design methodology for DC-DC converters with high insulation capabilities (up to 30kV) is proposed. The objective is to provide a power transmission function for IGBT drivers. To achieve this, a DC-DC full-bridge series-series (FB-SS) resonant converter with a high air gap transformer is selected and studied. This high air gap transformer (loosely coupled transformer (k)) is used for a high galvanic insulation system. Some transformer geometries are analyzed and compared for this specific application field. Therefore, in term of coupling coefficient of transformer (k), the analysis and the proposed investigations prove that pot core based transformers are suitable choices. Simulation results are presented and analyzed and experimental works are briefly described. Finally, the comparison between the simulation and experimental results are illustrated to validate the proposed methodology.

Inductive components play an important role in filtering the switching harmonics related to the pulse width modulation in voltage source converters. Particularly, the filter reactor on the converter side of the filter is subjected to rectangular excitation which may lead to significant losses in the core, depending on the magnetic material of choice and current ripple specifications. Additionally, shunt or series reactors that exists in LCL or trap filters and which are subjected to sinusoidal excitations have different specifications and requirements. Therefore, the core losses of different magnetic materials adopted in utility grid ac filters have been investigated and measured for both sinusoidal and rectangular excitation, with and without dc bias condition. The core loss information can ensure cost-effective passive filter designs and may avoid trial-error design procedures of the passive components parameters.

Multi-resonant converters like the CLLLC topology are known for their outstanding efficiency and high power density. Little information has however been published about the influences of secondary side diode junction capacitances on the output characteristics of the resonant converter. This paper presents a detailed analysis of these influences in the inductive working range and reviews practical design considerations of the converter. Therefore, experimental results of an inductive power transfer system, using a CLLLC resonant topology, are compared to theoretical time domain solution, showing significant effects of different semiconductor materials and devices on output power. These effects will be discussed and explained in detail by using measured key waveforms.

During standard robustness evaluations of a NPC type 2 IGBT power module a non-described effect in a Three Level NPC 2 topology was observed. A full description of that effect can help to protect IGBT power modules in this topology against blow ups and can help in a post mortem analysis to understand the reason for this. With a full understanding of that effect the lifetime of the inverter can be increased and the time and costs for qualification reduced.

The energy consumption of the information technology (IT) data centers and servers have been increasing rapidly for the past decade. In order to reduce global warming and conserve depleting sources of fossil fuel, hybrid wind-solar energy systems can be an attractive alternative energy source to supply clean and sustainable energy for powering the IT data centers and servers. To minimize the cost and power losses in individual power converter of the conventional hybrid renewable energy system, multi-input converters (MICs) are an attractive solution. This paper proposed a new quasi-resonant soft-switched MIC with integrated power factor correction (PFC) for hybrid wind-solar energy systems. The proposed MIC topology requires only one switch in each input module and all the switches are able to achieve zero voltage switching (ZVS) turn-on and zero current switching (ZCS) turn-off for individual and simultaneous operation for different operating conditions. The operating principles of the proposed circuit are provided. Results are given on a hybrid wind-solar energy system with 48V-output to highlight the performance of the proposed circuit.
