An approach of harmonics component analysis, portraying the presence of certain amount of harmonics at the inverter output terminal, has been indicated in this paper. Some unwanted impacts are caused by the harmonics such as unbalance and excessive neutral currents, interference in nearby communication networks and disturbance to other consumer, torque pulsations in electric motor drives are and so...
The paper derives a numerically efficient algorithm to predict the current harmonics from multiple hysteresis current-controlled PV generators in residential applications. The modeling approach starts by deriving the interdependent switching frequency resulting from the coupling between the PV line currents. Subsequently, using the analogue frequency modulation theorem, the harmonic line current is...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
