“…Electrical filters are very effective in common-mode noise prevention in single-converter systems [5][6][7][8][9] . However, in the back-to-back converter, common-mode noise is mainly generated by two sources, one of which, produced by the grid-side converter, is the reference for the other one, produced by the generator-side converter [10][11][12][13] .…”

This paper proposes equivalent circuits and a method for the estimation of the peak transient voltages at generator terminals in wind turbines equipped with back‐to‐back converters. Equivalent circuits as well as a way of phase‐to‐phase and phase‐to‐ground voltages estimation in back‐to‐back converter are presented. Proposed theoretical background is well confirmed by small‐scale measurements. It is shown and proven that phase‐to‐ground voltages represent a dominating threat for the wind turbine generators insulation. Copyright © 2014 John Wiley & Sons, Ltd.

“…This paper presents a simple circuit topology based on a commercial V/f inverter which generates three-phase voltage outputs with constant relation Voltage/Frequency that are rectified with a noncontrolled full bridge, being nowadays relatively low cost components for the desired powers. LC filters are widely used in power supplies of very different topologies, diverse functions (input or output filters), very variable powers and very diverse control strategies [3][4]. The use of non PWM inverters -sine wave or multilevel (see a.e [5]) -with passive filters let us reduce the presence of undesirable high frequency harmonic with any loss of efficiency.…”

Computer controlled power supplies are usually expensive when high performance (power, wide voltage range, low ripple factor and low response time) are required. This paper presents a simple and effective computer controlled DC system based on a commercial V/f inverter combined with a three-phase bridge rectifier and a LC power filter. Because of the widely variable frequency range of the V/f inverter when a wide range of voltage is required, amorphous or ferromagnetic core coils are avoided, and air core coils become an excellent solution to implement the filter and increase the efficiency of the power system. The proposed method for designing the LC filter is based on the full dynamic model of the filter-load set and the selection of the desired poles of the system according to the load to be coupled. The proposed topology lets obtain good time responses (setting time less than 100 ms) and good ripple factor (less than 1%) without any overshooting, even when low voltage output is required.

“…Thus far the technical literature has mainly dealt with the efficiency of the inverter output harmonic filters and filter types for two-level inverters [5], [6] and the DC-link [7]. Multilevel inverters without output harmonic filters have been reported [8].…”

A drive train system (DTS) powered by a battery and driving a permanent magnet synchronous motor (PMSM) is discussed in this paper. A two-level, three-phase conventional inverter with no harmonic filters on both AC and DC sides is used as means of power conditioning. This DTS is modeled as a double oscillator according to the mechanical part in an electric vehicle. Two inverter modulation schemes are applied, namely, a hysteresis scheme (non-deterministic) and one based on sinusoidal-triangular waveforms (deterministic). The influence of these modulation schemes on the performance of the DTS is determined by assessing the level of inverter generated harmonics flowing from/to the battery (electrical part) and the motor (mechanical part). The simulated results presented in the paper indicate that the absence of filters can be partly retained by a dispersion of the harmonic energy of the inverter generated spectral due to high frequency switching. This can be achieved by using a hysteresis control scheme and the impact of the filter-less inverter on the DTS performance is limited only by process specifications.
