They offer an output voltage that is predetermined and unchangeable without extraordinary effort. A variable output voltage regulator, on the other hand, can be programmed to any voltage desired within its range. These devices can be used for either variable DC power supplies, or to supply custom output voltages other than those allowed by the standard fixed voltages. Two similar This book will prove useful to electrical engineers, electronics professionals,.hobbyists, and students.Mechanical voltage regulators are used with DC generators, also with early alternators. One shown at right is adjustable; this one is sealed and must be replaced if it gets out of calibration. this is the function of the mechanical voltage regulator. Mechanical Voltage Regulator — As noted earlier, the field coils of the generator become magnets only when current flows through them. What if you could turn off the current to the coils when the battery is fully charged? And what if you could Voltage regulators Fixed voltage types eg 78, 79 series Voltage regulator IN OUT | | COM V in Variable DC \ 220 nF V out voltage 10,000uF 100 n –O O * Variable voltage types eg 317, 338 series Adjustable voltage.regulator |N ADJ V in Variable DC voltage 10,000uF [220 nF | R * oO 2 Vout = 1.25 ( '#) + IADjR2 Select R1 and R2 so that IA > 4 mA Opamp standard circuits v = closed loop a.c. gain fo = low frequency 3dB point e = input voltage Rin = input impedance eo = output Whether the DC power originates with a battery or has been converted from widely available AC power, a voltage regulator is usually required to provide a steady DC voltage for a variety of load conditions. Figure 63.1 illustrates the place of voltage regulation in a typical power supply. Although one may still find it useful to design and construct voltage regulators with VAC IN RECTIFIER discrete devices, today's precise but robust, bipolar monolithic voltage.regulators make design a The positive adjustable series regulator (LM317) and the negative adjustable series regulator (LM337) allow the user to design the desired output voltage. Figure 427 is a common circuit configuration for the LM317. The LM317 requires a positive dc input voltage resulting in a regulated positive dc output voltage. The LM337 requires a negative dc input voltage resulting in a regulated negative dc output voltage. The regulated output voltage for the circuit is calculated using Formula Voltage Regulator Circuit Manual highlights the techniques in DC regulator design. This book contains seven chapters that cover different circuit types, from the simple incorporation of silicon chips to the complex IC manufacturing..
