Engineers have been struggling with high dynamic range signals for decades. Dynamic range refers to the difference between the smallest and largest amplitude excursions of a signal. Imagine that you are making a measurement and most of the time the signal is in the millivolt range. Still, occasi...
For example, suppose you wanted to plot a sinusoidal waveform of 20-volts peak amplitude versus time. Using the equation 4–1, ei=20 Vsinθ the instantaneous value of voltage at any value of theta into the cycle can be determined. To help you understand this concept, the instantaneous...

Energy Management Systems for Hybrid AC/DC Microgrids 13.4.3.1 Node Voltage Magnitude for AC and DC Microgrids AC and DC node voltages should be within minimum and maximum standard ranges. (13.7)0.95=vn,tAC−min≤vn,tAC≤vn,tAC−max=1.05P.U (13.8)0.95=vn,tDC−min≤vn,tDC≤vn,tDC...
In alternating-current (AC) circuits, the voltage alternates between a certain maximum voltage and corresponding maximum negative voltage. This also applies to the current in AC circuits. The simplest representation of these variations with time is a sinusoidal graph. ...
Figure 1. The measurement setup. The Dewesoft SIRIUSi acquisition module is compact and robust - designed for field operations. The module integrates a high-end signal conditioning circuit with all the necessary features, such as: selection of AC or DC coupling, ...
At the same time, it is very useful to provide a short pulse to the base to make the turn-on as fast as possible and to reduce the dynamic saturation phenomenon. The pulse is achieved by using the capacitor and the Zener diode in Figure 6. Figure 6. Proportional driving schemati...
The two inputs are approximately equal at this time. The make-before-break disable characteristic of the OPA2690 ensures that there is always one amplifier controlling the line when using a wired-OR circuit like that shown in Figure 41. As both inputs may be on for a short period during...
While the power supplied to light string 100″ is DC, for AC operation a single diode 513 may be used as a half-wave rectifier to supply DC to this circuit. Alternatively, the output from a bridge rectifier could be used to supply the input power for full wave DC operation from an AC...
