The power factor is thought of as lagging when the load current lags the load voltage (inductive) and leading when the load current leads the load voltage (capacitive). The real power can also be found from the apparent power by multiplying the apparent power by the power factor: The real...
PCB ringing is an unwanted oscillation of voltage or current in a circuit board. During the signal transition from low to high or high to low, the voltage doesn’t immediately stabilize at the desired level; instead, it oscillates briefly before settling down. This oscillation creates a series ...
The reactance and the resistance cause a voltage drop in the transformer winding which depends on the load current supplied and the effective impedance of the secondary windings. Ohm’s law directs that V=IZV=IZ And this explains that an increase in the secondary winding current leads to an ...
The method involves using a circuit which influences the switching edges of a pulse-width modulated signal: a signal (8,9,12) representing the current in the battery leads to the inductive load, e.g. of electromagnetic valve, is detected and fed back to the input of the circuit An ...
The conventional electrical grid faces significant issues, which this paper aims to address one of most of them using a proposed prototype of a smart microgrid energy management system. In addition to relying too heavily on fossil fuels, electricity thef
Voltage magnitudes Vj at generators nodes jA{n þ 1,y,n þ m} are regulated by internal controllers to constant values, and the sum in equation (1) therefore contains both quadratic and linear terms in the unknown load voltages VL ¼ (V1,y,Vn). The symmetric coefficients Bij ¼ ...
As the motor picks up speed, the resistance (and reactance) increases so that the current inversely decreases. Figure 3. Measured resistance of motor windings between T-leads, configured for 480 V. Reverse Voltage, or Back EMF When the motor runs at full speed, a load is placed on the ...

Therefore, thanks to the use of PV and the concept of 2D power channels, we can verify that there is a real oscillation of energy between the source and the load through each channel and that it cannot be perceived through its computation via the voltage and current at the terminals. In ...
In addition, another drawback is the inability to prevent primary voltage harmonics from propagating into the load side. The SST with DC-link capacitor includes three stages. First stage is an AC/DC converter which is utilized to shape the input current, to correct the input power factor, ...
