design and limitations of practical power supplies with IC regulators. You should refer to Chapter 6 in H & H for background on this material. The D.C. power supply block diagram: This is a 100 Vac “line" voltage . Example: Design a regulated power supply using a full-wave bridge rectifier and a 1000 ?F capacitor.
The category of DC power supplies discussed in this section changes AC line voltage into DC voltages. The most common and versatile regulated DC power supply is the constant current (CC) or constant voltage (CV) type which as the name implies can provide either a constant current or constant voltage within a certain
In practice, d.c. power for electronic circuits is most conveniently obtained from commercial a.c. lines by using rectifier-filter system, called a d.c. power supply. 17.1 Ordinary D.C.

Summary-A new form of transistor series regulated power sup- ply is presented which permitsunusually good performance char- acteristics to be realized with simple and economical circuitry. Expressions are given for the open-circuit output voltage and the output resistance in terms of the supply voltages and the circuit.
EE323- Regulated Power Supply. Chapter 24 - Malvino. 107. CHAPTER 5: REGULATED POWER SUPPLIES. A regulated power supply can be built using a simple zener diode as a voltage regulator. Reverse breakdown voltage of the zener diode is used to hold the output voltage constant at a certain load condition.

Effects of Poor Regulation. The effect of poor regulation (or stabilisation) of the supply can be seen in Fig. 1.3.1 which shows graphs of output voltage (VDC) for increasing load current (I) in various versions of a basic power supply. Notice that the output voltage is substantially higher for full wave designs (red and yellow).
A regulated power supply is an embedded circuit; it converts unregulated AC into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits. The output from the regulated
