Der inländische ZahlungsverkehrIf the output current is made to circulate in an auxiliary winding suitably coupled with the original field winding, the net result can be an increase of the total field, so the increased electromotive force compensates for the previously observed voltage drops; thus the output voltage remains essentially constant.

Book 1991ces four of the important characteristics of the power supply: • Stability of the feedback loop • Rejection of input-voltage ripple and the closely-related transient re sponse to input-voltage perturbation • Output impedance and the closely-related transient response to load perturbation • Compatib

Analysis of Power Cells with Duty-Ratio Control at Variable Frequencythe book are boost, Ćuk, and SEPIC.) As we shall see, in the Porter cell the duty-ratio control is achieved by driving the isolation transformer of the cell into saturation in each cycle and by varying the drive frequency.

General Small-Signal, Low-Frequency Analysis of Switching Regulators the switching cell is no longer an independent variable; it is determined by other functional blocks in the closed-loop system. The system shown in Figure 3–1 operates as follows. The input to an error amplifier . is an error signal: the difference between the output voltage . and a reference level

State-Variables-Averaging Methodntribution to the dynamic analysis of switching structures and has been adopted by other investigators (e.g., , ). Because of this, and in spite of some unfavorable opinions , this method was considered indispensable in determining the essential features of switching power cells. As shown i
