Least squares method for indentification of IGBT thermal impedance networks using direct temperature measurements

State-of-the-art methods for determining thermal impedance networks for IGBT (Insulated Gate Bipolar Transistor) modules usually involves the establishment of the relationship between the measured transistor or diode voltage and temperature under homogenous temperature distribution across the IGBT module. ...

A design of a dual-band bandpass filter based on modal analysis for modern communication systems

A dual-band bandpass filter (BPF) composed of a coupling structure and a bent T-shaped resonator loaded by small L-shaped stubs is presented in this paper. The first band of the proposed BPF covers 4.6 to 10.6 GHz, showing 78.9% fractional bandwidth (FBW) at 7.6 GHz, and&...

Comparison of IPMSM parameter estimation methods for motor efficiency

Efficiency of an IPMSM motor is influenced by the operating point (OP) of the machine. The optimal operating point can be found by using either direct search methods or model-based methods. Model-based methods are sensitive to parameter uncertainties of the equivalent circuit of th...

Improved bidirectional DC/CD converter configuration with ZVS for energy storage system: analysis and implementation

This study proposes a novel design of soft-switching based bidirectional converter for the applications in energy storage systems. By implementing an additional auxiliary circuit to the conventional non-isolated converter, the proposed converter inherits better efficiency with minimised turn-on losses....

A compact lowpass filter for satellite communication systems based on transfer function analysis

This paper presents a very efficient design procedure for a high-performance microstrip lowpass filter (LPF). Unlike many other sophisticated design methodologies of microstrip LPFs, which contain complicated configurations or even over-engineering in some cases, this paper presents a straightforward ...
