The LM78XX series of three-terminal positive regulators is available in the TO-220 package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut-down, and safe operating area protection. 78xx 79xx voltage regulators
7805 is popular for Embedded Systems and 7905 is sometimes used for the Dual Supply needs in such Microcontroller cards with Mixed Design sub-sections like A/D or Opamps.
Linear Circuit Design Handbook, edited by Hank Zumbahlen (Newnes, 2008), bridges the gap between circuit component theory and practical circuit design. Effective analog circuit design requires a strong understanding of core linear devices and how they affect analog circuit design.
A Resource of Value for Industrial Engineering. Here is an Online Textbook for learning advanced process control concepts. The Reference includes Sample Process Control Course, Instrumentation for Process Control, WEB-Based Educational Resources for Process Control and Process Operability.
The Process Control Education Web Site
The material above can also be found on the -Process Control, 2nd Edition, McGraw-Hill, 2000 - ISBN 0-07-039362-1 a textbook by T. Marlin.
Eddy Current Testing (ET) and Infrared/Thermal Testing (IRT) are Interesting Areas where experienced designers can build and manufacture Test Equipment. These pages have NDT study material for college and Science Educational Pages for High School.
EMI RFI Noise Filters are required in two situations, to prevent EMI from an Electronic Equipment Like A Dimmer, Thyristor Drive, SMPS or Switcher affecting other Modules in a System or Neighboring Equipment.
The Second Situation is when a Sensitive Equipment Like a Medical Apparatus or Precision Measuring Instrument has to be Immune to any Noise from outside, as it can affect performance.
Sometimes it is Accuracy that can get affected, but some electrical jolts can damage or desensitize fine sensors or positioning systems.
The Electric double layer capacitor has the main use of a Charge Reservoir. That means a large amount of electrical charge in a small footprint. These charge/discharge quickly unlike the battery, There is no Electrical Energy to Chemical Energy Transformation and back, like in batteries. It may need caution in design and usage as they may carry a lot of punch.
Also known as Ultracap, Goldcap, Supercap - Electric double layer capacitor, In Farads, like batteries, Energy Reservoirs or eFlywheel.
This is an educative and important guide for Electrical Equipment Safety. This can be also applied partially to Power Electronics and Home Energy Systems. Electronic Equipment also have to be maintained by Calibrating them and protecting them from environmental parameters like dust, grime, direct sunlight, moisture, humidity, sea wind (brine), corrosive fumes and chemicals. They should not be even placed near machines like a big lathe, sub-sonic or low frequency vibrations. - delabs notes
An Oscilloscope could be used to monitor the test points and the output of systems or modules. A function generator injects the input or simulates a input condition. It could be Sine Wave, Triangle Wave, Ramp or Square wave. Frequency, Amplitude and Duty cycle (square) are variable settings.
For radios and amplifiers a simpler set is used it is called "Signal Injector" and "Signal Tracer". In Digital System a Pulse Generator and a Logic Probe may be used.
delabs Notes
This is yet another Application Note of Exar found in- "Applications Data Book" June 1981. The availability of low cost dual or quad operational amplifier IC's have made the operational amplifier based active filter techniques cost effective over conventional passive filters.
The recent availability of programmable quad operational amplifiers such as the XR-4202 or the XR-346 have provided the active filter designer with the flexibility to externally program gain-bandwidth product, supply current, input bias current, input offset current, input noise and the slew rate.
This is another versatile and flexible chip. I could design current sources, voltage to current transmitters, level translation and many more. You can think of applications beyond the Power Electronics Scope with this. Input voltage up to 40V, Output voltage adjustable from 2 to 37V, Output current to 150mA without external pass transistor and Adjustable current limiting.
"The circuit provides internal current limiting. When the output current exceeds 150mA an external NPN or PNP pass element may be used. Provisions are made for adjustable current limiting and remote shutdown."
