9. Since this difference is equal to the voltage of a properly designed solar cell, luminescence is the key indicator of material quality for solar cells. 对于太阳能电池,因为费米能级差等于电池的伏特数,所以发光性能是电池材料质量的一个重要指标。
For a non-effectively earthed system the maximum phase-to-earth voltage is equal to the maximum line voltage (see Chapter 1). Consider a 132 kV system with a maximum line or phase-to-phase voltage 110% of the nominal system voltage 1. effectively earthed and 2. not effectively earthed: ...

If one of the voltages is greater than or equal to 207 V and no undervoltage alarm is generated for switches that use the same power source, restart the centralized monitoring board. If the fault persists, replace the board. (During the replacement, remove the switch statu...
188 V DC to 288 V DC; rated value: 240 V DC Maximum input current 18.5 A Rated output voltage 53.5 V DC Rated output power 3000 W NOTE: When the AC input voltage is lower than or equal to 175 V AC, the rated output power reduces to 1500 W. Ordering Information To place an...
At the time when capacitor voltage is equal to the source voltage , no more current flows. 当电容电压等于电源电压时,就不再有电流流动 www.en8848.com.cn 7. The spectra of the main elements of the drain-source voltage can be found in Fig. 20. 图20描述了漏源极电压主要原理产生的电磁干扰...
and portnprovides a connection to the center of the wye. Port~is an expandablethree-phase portrepresenting the three phases,a,b, andc. The current is positive if it flows from the center of the wye to the positive terminal, and the voltage across each phase is equal to the difference ...
Hence a small voltage corresponds to a small displacement of a charge in an electric force field. It is useful to consider the inverse operation of (1.2), which expresses work as an integration in a force field, that is, V = ∫ E · dl. The inverse operation gives the force as the ...
In most cases the alternating voltage is sinusoidal and the frequency is close to or equal to the resonant frequency of the structure. Generally speaking, there are three driving schemes as follows: (a) Alternating voltage driving If an alternating voltage, V1 sin ωt, is applied between a ...
