Assessing Harmonic Impedance by Synchronously Layered Distortion Waves;

The impact of harmonic impedance on the relationship between harmonic voltage and harmonic current emission limits was discussed based on a comparison between IEC 61000-3-6 and GB/T 14549-93.

The armature reaction and differential leakage reactance in free space of a long stator linear synchronous motor;

The relationship between currents of Filter Commutated Converter and the harmonic characteristics of multifrequency AC/DC interconnected systems based on New-Type converter transformer have been studied with ideal models by means of theoretical analysis and matlab simulation.

To give Pspice simulation and experiment results, this paper analyses the harmonic characteristics of three-level inverters using double-Fourier series, and compares it with that of two-level ones, based on the principal circuit topology and its operating principles of three-phase SHPWM three-level inverter with clamp diodes, which shows many merits of the three-level one.

Further more the switching loss and harmonic characteristics of these SVPWM strategies are compared,the optimal SVPWM of the noneswitching areas of phase voltage lagging behind sinusoid voltage peaks 30° is selected according to the load characteristic.
