A lot of harmonics exist inherently in the front end of 3-phase rectifier feeding Variable Frequency Drive (VFD) of 3-phase induction motor due to the nonlinearities behavior in such loads. The harmonics cause energy losses and deficiency to the overall system. The goal of this paper is to reduce the harmonics for a variable frequency drive by calculating the equivalent circuit of the 3-phase induction motor and identifying the parameters of a passive filter, which is connected to the input side for the rectifier from the VFD converter. The equivalent circuit for the 3-phase squirrel cage induction motor is achieved according to the results of laboratory tests. The concept of point of common coupling (PCC) is implied into the calculations of harmonics and power factor. The performance of the VFD described is simulated using Matlab /Simulink (2008).

“…With the advent of single-phase bridgeless topologies, a similar phenomenon can be registered in three-phase connections. The most widespread and most used solution is the so-called 6-switch 3-phase PFC converter in bridge connection, thanks to the development and advent of new generations of SiC transistors [12][13][14][15][16][17][18].…”

This paper evaluates the performance of the high-voltage wide-band gap SiC power transistors equipped within 3-phase bridgeless 3 kW PFC circuit. The main aim of the study is the experimental evaluation of the dynamic properties and driving power requirements of the transistors, for which the parameters are similar. These are competing products from different manufacturers, while the selection criterion was the same type of package technology (7 pin D2PAK). Second, the effect of the transistor type was analysed in terms of the performance efficiency of the PFC circuit. Within the analysis, the driver circuit was constructed first, and adapted to high voltage transistor driving. During individual measurements, the driver remained the same, while gate-driver losses were analysed for individual transistors. The obtained results reveal differences related to requirements on driving power, as well as to the dynamics of transistors themselves. At the end of the paper, the evaluation of efficiency for different operating conditions of a constructed PFC converter is realized. The obtained results provide a more detailed overview of the dynamic properties of transistors and their impact on the resulting efficiency of the main circuit also in terms of driving requirements.

The aim of this work is to investigate the influence of circuit elements on the properties of the selected power factor correction (PFC) topology. Active or passive PFC serves to increase the power factor (PF) and reduce the total harmonic distortion (THD) of the mains current. As a result, the distribution network is lightened due to its interference caused by connected electronic devices. An important indicator of all electronic converters is efficiency. Therefore, the work deals with the analysis of possible efficiency improvements in conjunction with the use of technologically new active components. Detailed experimental analyses and optimization procedures are performed in terms of the influence of transistor structures (SiC and GaN) on the qualitative indicators of the proposed PFC converter for a wide operating spectrum. The synthesis of the obtained results is given, together with recommendations for optimal selection and optimal design of PFC main circuit elements with regard to achieving peak efficiency values.
