Field produced by each phase winding ElectricMotors

Wed, 22 Feb 2012 10:31:48 GMT

The aim of the winding designer is to arrange the layout of the coils so that each phase winding, acting alone, produces an MMF wave and hence an air-gap flux wave of the desired pole number, and with a sinusoidal variation of amplitude with angle. Getting the desired pole number is not difficult we simply have to choose the right number and pitch of coils, as shown by the diagrams of an elementary 4-pole winding in Figure 5.3. In Figure 5.3 a we see that by positioning two coils each of which...

Tue, 21 Feb 2012 10:36:37 GMT

Texas Instruments measures the noise characteristics of a large sampling of devices. This information is compiled and used to determine the typical noise performance of the device. These noise specifications refer the input noise of the op amp. Some noise portions can be represented better by a voltage source, and some by a current source. Input voltage noise is always represented by a voltage source in series with the noninverting input. Input current noise is always represented by current...

Building simple VLF radio receivers CircuitDesign

Tue, 21 Feb 2012 07:36:55 GMT

The very tow frequencies VLF are located between a few kilo hertz and around 300 kHz, depending on whose definition is used. For purposes of this chapter VLF represents the 5- to 100-kHz region. The reason for this seemingly arbitrary designation is that many ham-band and SWL communications receivers operate down to 100 kHz and only a few operate below that limit. A lot of radio stations are active in the region below 100 kHz, Perhaps the best-known station is WWVB on 00 kHz. This station is...

1443 AC Application Error Budget OpAmps

Fri, 10 Feb 2012 15:25:24 GMT

The error budget for an ac application will most likely be specified as total harmonic distortion, dynamic range, or signal-to-noise ratio. Assuming no internal noise, and no noise in the buffer op amp circuitry, the inverse of the dynamic range is the signal-to-noise ratio of the converter D A. Of course, noise is always present, and is measured with all input data set to zero. Noise will make the S N ratio decrease. The number of converter bits, however, is the overwhelming factor determining...

22 Core Parameters And The Effect Of An Air Gap Switchmode Power Supply 2

Sat, 04 Feb 2012 19:52:57 GMT

Figure 2.2.1a shows a typical BIH hysteresis loop for a transformer-grade ferrite core, with and without an air gap. It should be noted that although the permeability slope of the BIH loop changes with the length of the air gap, the saturation flux density at the combined core and gap remains the same. Further, the magnetic field intensity H is much larger, and the residual flux density Br much lower, in the gapped case. These changes are vety useful for flyback transformers, which use only the...

Some applications need the input current to be controlled, to prevent high current spikes when power is first applied. This could be to reduce damage to switch contacts by the risk of sparking. Clearly the inrush techniques just described could be used, but sometimes it is necessary to control the output power instead. For example, a circuit for driving one or two power LEDs from the AC mains could use a double-buck topology. But typical applications for this circuit are inside lamp housings,...

Graphical interpretation via phasor diagram ElectricMotors

We will look at the current phasor diagram as the slip is varied, for two motors, both having the same leakage reactance, XT. One motor will be representative of the 'low-resistance' end of the scale R2 0.1 XT while the other will represent the 'high-resistance' end R2 XT . As before, the voltage and frequency are constant throughout. The reason for choosing total leakage reactance as the common factor linking the two motors is simply that the current loci see below are then very similar, and...

75 Conclusions BoostConverter

Thu, 19 Jan 2012 03:27:40 GMT

The boost-buck is an ideal topology where the LED load voltage can be higher or lower than the supply voltage. It should also be used when the supply voltage is no more than 20 difference worst case from the LED load voltage. So if the LED voltage maximum is 20 V and the supply voltage minimum is 23 V, the difference is 3 V, and 3 20 0.15 or 15 , so a Cuk or SEPIC should be used. If the supply voltage is more than 20 higher, use a buck topology. If the supply voltage is more than 20 lower, use...

The conventional diode, capacitor, snubber circuit should not be used in the half-bridge...

Because power FET devices are not subject to the same secondary breakdown mechanisms that occur with bipolar devices, from a reliability standpoint, it is often considered that snubber components are not essential. However, in most FET applications, a small RC snubber network will still be fitted across the FETs to reduce RF radiation and meet the dv df limitations of the FET. With very high dvldt, some power FETs display a failure mode resulting from conduction of the internal parasitic...

31 Ideal Op Amp Assumptions OpAmps

The name Ideal Op Amp is applied to this and similar analysis because the salient parameters of the op amp are assumed to be perfect. There is no such thing as an ideal op amp, but present day op amps come so close to ideal that Ideal Op Amp analysis approaches actual analysis. Op amps depart from the ideal in two ways. First, dc parameters such as input offset voltage are large enough to cause departure from the ideal. The ideal assumes that input offset voltage is zero. Second, ac parameters...

stricted to the nonoverlapping mode, it is seen that the design for overlapping and crossing into nonoverlapping mode permits a larger range of DC input voltages and allows a larger on time at high input voltages. This latter permits the use of bipolar transistors, which would have difficulty operating reliably at the low on times close to the vicinity of their storage times. 5.6.7.13 Voltages, currents, and wire size selection for design example in overlap mode. Transistor currents and...
