The harmonic mitigation using shunt active filters are most widely used in industrial and commercial applications. In this paper a Multi-Level Inverter is considered as DSTATCOM to compensate harmonics. The mathematical modeling of the system and design of the controller using synchronous reference frame theory is also presented. The nonlinear load generally known as diode rectifier load and an...

Considering the fact that load distribution of the flexspline under alternating dynamic loads is complicated, and it’s difficult to measure the stress of the flexspline by experiment, a dynamic simulation model of harmonic gear drives is established to study the intensity of the flexspline in the operating process of harmonic gear drives based on finite element method. In order to decrease the ...

With the increasing penetration of power electronic equipment in modern residential distribution systems, harmonics mitigation through the distributed generation (DG) interfacing converters has received significant attention. Among recently proposed methods, the so-called active resonance damper (ARD) and harmonic voltage compensator (HVC) based on voltage detection can effectively reduce the h...

In this paper the active device for a class E amplifier is modelled as switch in series with a turn on resistance ‘Ron’. Assuming an ideal harmonic load is used the switch equations for the voltage and current waveforms are reviewed and then used to examine how ‘Ron’ affects the efficiency of dc to ac power conversion. This ideal harmonic network is assumed to have optimum input impedance at th...

The demand for accurate and reliable positioning in industrial applications, especially in robotics and high-precision machines, has led to the increased use of Harmonic Drives. The unique performance features of harmonic drives, such as high reduction ratio and high torque capacity in a compact geometry, justify their widespread application. However, nonlinear torsional compliance and friction...
