WebThe fundamental idea and meaning of small-Signal modeling for power supplies is explained and the small-signal transfer functions for basic converters and general compensation networks are explored. Negative feedback control is used in switched-mode power supplies to regulate the output at a desired value. The optimum design of the feedback control … The simplest TL431 regulator circuit is made by shorting the control input to the cathode. The resulting two-terminal network has a zener-like current–voltage characteristic, with a stable threshold voltage VREF≈2.5 V, and low-frequency impedance of around 0.2 ohm. Impedance begins to grow at around 100 kHz and reaches 10 ohm at around 10 MHz. Regulation of voltages higher than 2.5 …
