Sinusoidal voltage source

This op-amp circuit is a Schmitt Trigger with trigger points at approximately 7.5 V. A sinusoidal voltage source will be used to swing the input from +14 V to -14 V and from -14 V to +14 V a few times. The frequency of the source is 1 Hz. This low frequency is chosen to eliminate the effects of the op-amp slew rate on the Schmitt Trigger performance. If you...

Utility power distribution is intended to be a constant frequency (e.g., 60 Hz in North America), sinusoidal voltage source. Harmonic content is considered an undesirable distortion. The square-wave output of the simple converter illustrated in Fig. 10.5 would contain all of the odd harmonics, but the amplitude of each harmonic decreases as the harmonic number increases. The harmonic content of the...

The dielectric relaxation properties in nano-PS with different thicknesses have been investigated recently over a wide range of frequency and temperature [160,161]. The dielectric properties of the PS samples were measured in the 20-Hz to 1-MHz frequency range and in the 173 to 493 K temperature interval. For all the dielectric measurements, the amplitude of a sinusoidal ac-voltage source was maintained 1 V so that the average electric field across our sample was of the order of hundreds of volts per centimeter depending on the sample thickness. It was verified that the response was linear with respect to the ac-voltage amplitude such that a linear response analysis could be utilized for our sample. 

The power converter design will rely on Caterpillar s experience with state-of-the-art solid-state power converters that employ switches, inverters and pulse width modulation to shape a sinusoidal voltage and current in time with the existing power source on site. 

Most power systems in the oil industry do not have variable speed drives and so the AC supply is a highly dependable and simple source of sinusoidal voltage and current. Little or no harmonics are present. If a large variable speed drive is required, and an inverter or thyristor controller of some form is used, then the combination of these equipments will cause harmonic currents to be drawn from the supply. 

High-power inverters were initially developed for the long-distance transmission of power from a three-phase source to a remote three-phase sink using a DC overhead transmission line or cable. Early DC power transmission used mercury arc thyratrons (gas-filled values or tubes), which functioned in a manner very similar to the early types of thyristors. The on state of the valves was controllable, but the off state was determined by natural commutation made available by the sinusoidal voltages of the sink power system, see Reference 13. A brief description of three-phase inverters follows.

The IDT behaves as a sequence of ultrasonic sources. For an applied sinusoidal voltage, all vibrations interfere constructively only if the distance all between two adjacent fingers is equal to half the elastic wavelength. The frequency Fo = Vaw/>1 = Faw/o that corresponds to this cumulative effect is called the synchronous frequency or the resonance frequency. The bandwidth of an IDT is narrower, when there are more fingers. When IDT is used the AW velocity is determined by the plate material and orientation, while wavelength depends only on the ITD periodicity.
