Silicon carbide is an excellent candidate when high temperature power electronics applications are considered. Integrated circuits as well as several power devices have been tested at high temperature. However, little attention has been paid to high temperature passive components that could enable the full SiC potential. In this work, the high-temperature performances of different passive components...
Reliability-oriented design has been proved to be a kind of effective design methodology for power electronic equipment. This paper proposes a design method to obtain the value of inductance and capacitance sets that obtain high capability, power density, high reliability of an LC filter in buck converters through a multi-objective optimization way. The cutoff frequency, lifetime of capacitor and...
With the commercialization of wide bandgap power devices such as SiC MOSFETs and JBS diodes, power electronics converters used in the harsh environments such as hybrid electric vehicles and aerospace attract more and more attentions. The low loss, high temperature and fast switching capabilities are utilized in the converters to improve the power density and efficiency. However, the EMI problem caused...
A small modular unit for a power converter system with long lifetime DC-link capacitors is proposed. To reduce the ripple current stress of DC-link capacitors and to improve their lifetime by limiting temperature rises, low phase-to-phase-impedance busbars are selected. Consequently, in a power converter system whose size is 101 L, operating at a rated power of 100 kVA, DC-link capacitors achieve...
This paper discusses the design of a setup for short-circuit (SC) testing of 10 kV 10A 4H-SiC MOSFETs. The setup can achieve voltages up to 10 kV and currents in excess of 100A. The main objective during the design was to obtain low parasitic inductance throughout the setup, while at the same time, reduce the complexity and size of the setup by avoiding series connection of DC-link capacitor and by...
Design of a Non-Destructive Test (NDT) set-up for short-circuit tests of 1.7 kV, 1 kA IGBT modules is discussed in this paper. The test set-up allows achieving short-circuit current up to 10 kA. The important objective during the design of the test set-up is to minimize the parasitic inductance and assure equal current sharing among the parallel connected devices. Achieving of a low inductance level...
Along with the development of energy storage technology, lithium battery management system became more and more concerned. As one of the key technologies for energy storage system, it is more extensive applied especially in the electric car field. In this article, an inductance balancing method based on the boost topological structure was design to control lithium battery system, including battery...
Series resonance (SR) method was investigated for the realization of 100 mH inductance at 1 kHz in VNIIM and MIKES. Practical details of the application of this method and comparison with the results of realization by the Maxwell-Wien Bridge method are presented. Results showed that 1 s uncertainty of the 100 mH realization by SR method at 1 kHz can be at the level of parts in 106.
This paper describes the design and testing of a two-channel 52-kW pulsed load. Its main feature is exceptionally low parasitic inductance, on the order of 200 nH. Such low inductance was needed in view of microsecond high-current pulses; it was realized by a compact design and careful layout. Small size is a prerequisite for minimizing the inductance; it was achieved by forced liquid cooling. Non-inductive...
This paper is concerned with electrical energy transmission by measns of inductive coupling between two spiral coils with amorphous magnetic fibers.
