PURPOSE: To display an image of high quality by preventing shadowing. ;CONSTITUTION: A driving voltage generating circuit 20 generates a DC voltage on the basis of two voltages VH and VL and supplies the DC voltage to a common electrode. The actual voltage at the common electrode is detected...
3.1. Modulation Strategy of Three-Phase Reference Voltages As explained in Section 2, the two circuit configurations of the H7 inverter system reduce the CMV only for the duration of one of the zero-voltage vectors. The topology in Figure 1a,b achieves CMV reduction only for the 𝑉7V7 and...
Brownouts are commonly caused by overuse on the grid or utilities temporarily cutting back on available power. Over voltages are commonly caused by wiring faults within a home, generators, or downed power lines. Effect on A/V Equipment: When subject to extended periods of voltage under 90V or...
In the present note we provide the general solution of a question concerning non-symmetric AC star circuits that came up in a practical application: Given a non-symmetric AC star circuit, we need the quantities of the line voltages. For ... C Eggert,R Gäer,F Klinker 被引量: 0发表:...
In electrical engineering, common-mode interference is the term used for interference voltages and currents on the connecting lines between electrical components that occur with the same phase position and current direction both on the forward line and the return line between these components.

Adjacent loads turning on or off, power factor correction capacitor banks or even distant weather can generate transient voltages on distribution systems. These transients, which vary in amplitude and frequency, can erode or cause insulation breakdown in motor windings. Finding the source of these ...
As a result, it is shown experimentally that both three-phase line-to-line and line-to-neutral output voltages look purely sinusoidal as if the inverter system were an ideal variable-voltage, variable-frequency power supply when viewed from the motor terminals. This results in complete solution ...
