Power Stage Transfer Function

With this understanding, we can build the final transfer functions presented in the next section. [Pg.283]


The control-to-output transfer function is a product of the transfer functions of the PWM, the switch and the LC filter (since these are cascaded stages). Alternatively, the control-to-output transfer function is a product of the transfer functions of the PWM stage and the transfer function of the power stage . [Pg.284]

The frequency response of a single stage electronic amplifier was calculated in Section 4.3 as an example of solving several simultaneous complex equations. The result of this was a Bode plot of the magnitude and phase angle of the response as shown in Figure 4.7. This is repeated here for reference as Figure 9.47. Such a network transfer function is known to be the ratio of numerator and denominator polynomials in powers of the frequency /, the independent variable, i.e. [Pg.424]

Chromatography is a powerful separation method because it can be carried out easily under experimental conditions such that the two phases of the system are always near equilibrium. This is because the kinetics of the mass transfers between these phases is usually fast. The separation power of a column, under a given set of experimental conditions, is directly a function of the rate of the mass transfer kinetics and of the axial dispersion coefficient. The scientists involved in the development of stationary phases for chromatography have produced excellent packing materials that permit the achievement of a very large number of equilibrium stages (i.e., theoretical plates) in a column. Thus, as we show later in Chapters 10 and 11, the thermodynamics of phase equilibria is often the main... [Pg.221]

A further means by whieh to deal with linear reeursions and transfer-matrix approaches is by way of generating functions. One introduees generating funetions with stage-Z- counts appearing as coefficients of a dummy variable z raised to the power L. For example, for Kekule structure counting. [Pg.69]

Interestingly, it had been recognized at a very early stage that electronic absorption spectroscopy provides a powerful tool for the detection of interaction between two different functional groups especially if these have pronounced electron donor (D) and electron acceptor properties (A) respectively. Interaction between D and A groups is then expected to lead to one or more new electronic transitions of the charge transfer (CT) type. (D.A + hV(.( D. A ) and the presence or absence of such CT transitions thus in... [Pg.182]

A detailed treatment of the axial power distribution local heat transfer, two-phase mixture dynamics, and coupling with the rest of the reactor coolant system requires the use of complex computer models. Figure 3.2-1 compares the predictions based on Eq. (3.2-1) with code calculations for a Zion station blackout scenario compounded by failure of turbine-driven auxiliary feedwater (the so-called TMLB scenario). As indicated by the comparison, the exponentially decreasing function defined by Equations 3.2-1 and 3.3-2 is a reasonable approximation for the water level in the core region during this stage of the accident. [Pg.304]
