These are high-voltage, high-current Darlington transistor arrays. Each consists of seven NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads.
Many may already know about these EE Educational pages with Circuits of J. B. Calvert. These pages are valuable as they are like a summation of Important and Practical Sections in many EE Subjects. If you want to master the basics of EE, these pages will propel you in the right direction.
A Wealth of Information is at the site - Dr James B. Calvert Associate Professor Emeritus of Engineering, University of Denver and Registered Professional Engineer, State of Colorado. An EE-Encyclopedia Almost..
The interactive and animated applets are part of the Introductory Course on Power Electronics taught by Prof. Kolar at the ETH Zurich.
Interactive Power Electronics Seminar Power Electronics Circuit Simulation Applets to See - are the simple Buck-converter and the Rotating Three-Dimensional Field More pages of Compulsory Reading for Students
These old publications, from 1966 and 1963, respectively, are some of the finest works on op amp theory that I have ever seen. Nevertheless, they contain some material that is hopelessly outdated.
This includes everything from the state of the art of amplifier technology, to the parts referenced in the document - even to the symbol used for the op amp itself:
CARACA is a home automation project based on a net of interconnected programmable circuits suited to perform different tasks like switch on/off appliances, decode commands from Ir remote control units, control thermostats, measure temperature and more.
Every node of the net communicate each other through a robust protocol (CANBus), and the status can be monitored by a PC possibly connected to the Internet.
ViPEC is a powerful tool for the analysis of high frequency, linear electrical networks. It takes a schematic description of the electrical network and performs a linear analysis in the frequency domain.
The output is in the form of port parameters (S, Y or Z) with results presented on a user defined grid, Smithchart or table. It can also be used to compute other characteristics like stability factors and group delay.
Single plate induction cooker demonstration board Uses ST7LITE09 and STGW40NC60WD (40 A, W series).
The design is entirely controlled by a simple ST7FLITE09Y0 8-bit microcontroller, which provides the PWM driving signals, communicates information to the user interface, and drives the fan and relay control to the plate feedback.
With Single Voltage Flash Memory, Data Eeprom, Adc, Timers, Spi Active - ST7LITE09Y0 8-Bit Mcu
Lab Experiments using A/D and D/A cards. PC Interface. Using Matlab, Learning PID control. DC Motor control. Hovercraft project with PWM and Fans as Actuator of control system, Uses NIDAQ Interface.
A virtual 8051 is interfaced with virtual peripherals such as a keypad, motor, display, UART, etc. The student can write 8051 assembly code, step through the code and observe the effects each line has on the internal memory and the external peripherals.
The student can learn how to scan a keypad, multiplex 7-segment displays, control a motor and count its revolutions, etc.
