A very simple and fast method for computing power systems maximum loading points is proposed in this paper. These points are simply computed through repeated load flow solutions. The main contribution resides in the appropriate use of a special load flow with step size optimization and the extraction of useful information from it, which guides the search for the desired maximum loading point. The...
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...
The paper presents the design and implementation of input/output interface circuits, fully compatible with low-voltage differential signal (LVDS) standard. Due to the low voltage differential transmission technique, the low power consumption and high transmission speed are achieved at the same time. The transmitter is implemented by a closed-loop control circuit and an internal bandgap voltage reference,...
We described an EPC (electronic power conditioner) developped for French Telecom administration for an 12 GHz 20 W TWTA (Travelling wave tube amplifier). • EPC1 requirements are submitted and the electrical design which used MC2 (currentcontrol- modulator) control is described with associated results. An simulation model is proposed. Particular technological points such High-voltage transformer, hybrid...
