Types of Transmission Line

Image
  Transmission line is a cable that transfer Electromagnetic wave from source to destination. Conventional electrical cables are adequate for carrying low frequency alternating current (AC), such as mains electricity, which reverses direction 100 to 120 times per second, and audio transmissions.  however, Electrical cables cannot be utilized to carry radio wave flux over around 30 kHz since the energy starts to radiate off the cable as radio signals, resulting in power dissipation. Radio frequency currents also generally reflect from cable irregularities like connections and joints and flow back across the cable towards to source. Typically transmission lines are distinguished by having uniform cross sectional dimensions over entire length, resulting in a standard impedance, known as the characteristic impedance, to minimize reflections. Parallel lines (ladder lines, twisted pairs), coaxial cable, and planar transmission lines such as stripline and microstrip are exampl...

LCD DriverPCF8562TT

Image
  Liquid Crystal Display (LCD) is observed and seen everywhere. From homes to offices, they are popular throughout the world. An ample amount of time was taken to develop this innovative technology, first accidentally invented in 1888 by Friedrich Reinitzer, an Austrian botanist. However, formally being developed in 1968 by the RCA Corporation. PCF8562TT is used to drive these LCDs by driving segments or dots so that LCDs operate without any signal contention being instructed by the microcontroller and prevents matrix damage. In other words, PCF8562TT provides an interface between the microcontroller or microprocessor and the LCD by I2C bus.     Why use PCF8562TT ? PCF8562TT is a device that can be used with any type of LCD. It has low multiplex rates and can also be used for the LCDs having backup planes of up to 4 and segments of up to 32. The aforementioned is well-suited with almost every microcontroller and uses I2C serial communication as well as accepts ...

AH9485/86 1ɸ SMART DC MOTOR DRIVER

Image
  Machines incorporate generators and motors which are still widely used in a variety of systems to this day, generators and motors require proper mechanisms to operate thus mitigating any damage or loss. Systems of DC Machines have been frequently used in applications requiring a wide range of precise control of both motor output and motor speeds. Despite the development of solid-state ac drive systems DC Machines still represent significant value through both their versatility and simplicity. A motor driver is required to start a DC motor when utilizing Bluetooth, microcontrollers, or any other wireless system. These systems usually operate on a current of a few amperes while motors especially DC require certain high amperes of current which is needed to be provided by some external source. The purpose of a motor driver is to amplify the current being provided by the aforementioned low amps systems to drive the motor smoothly. In other words, motor drivers act as an interface...

IRG4PC50UPbF

  Insulated gate bipolar transistor (IGBT) is a semiconductor device that can be used for switching purposes. It is a basic electronics components distributor but its switching speed and efficiency are much better than other transistors. Advancements in technologies are being observed due to new innovatory ideas. One of the optimized designs is the 4th generation, High-speed IGBT   -IRG4PC50UPbF, manufactured by the International rectifier. The international rectifier is a leading manufacturer that produced many electronics power supplies the device.   How IGBT works?   IGBT is a combination of MOSFET and BJT. Three terminals of IGBT are gate, collector, and emitter. Three terminals are connected to three different metallic layers. A semiconductor layer is providing insulation to the gate terminal layer. Four layers of semiconductors are sandwiched together to form an IGBT module. For understanding the functionality of the module, If the gate voltage is incre...
