  • Incompatibility of Power Factor Correction Capacitors with AC PWM Drives
    factor as seen by the user's line. A bank of these oil-filled or dry type AC capacitors usually reside in a conspicuously placed metal enclosure nearby the motor. Beware of retrofitting any AC controllers (including VVI and CSI types) to existing induction motors! If the installation is not thoroughly
  • Watlow SCR Power Controllers and Ohio Semitronics Watt Transducers
    The Ohio Semitronics PC5 category of transducers measures True Power (Watts) in an AC single-phase or three-phase power system and provides an isolated DC analog output that is proportional to the electrical power being consumed in a load. There are thousands of PC5's being used worldwide
  • Flexible AC Transmission Systems: Modelling and Control
    Flexible AC Transmission Systems: Modelling and Control. Presenting the modelling of the latest FACTS controllers for power flow control, compensation and power quality in power system analysis, this book comprehensively covers a range of power-system control problems.
  • AN1162 - Sensorless Field Oriented Control (FOC) of an AC Induction Motor (ACIM)
    is to present one solution for sensorless Field Oriented Control (FOC) of The key to understanding how field oriented control (R) Digital Signalinduction motors using a dsPIC works is to form a mental picture of the coordinate Controller (DSC). reference transformation process. If you picture how an AC
  • Selecting Explosion-Proof Motors and Variable Frequency Drive Controllers for Hazardous Environmental Applications
    important to the success of a XP motor operated on variable frequency drive power. The proper application of variable-frequency drive controller power to AC induction motors can be difficult even in relatively simple applications. When using a variable-frequency controller, the non-pure sine wave
  • Tranformerless Power Supply TechBrief
    , there are applications where the PIC12/16/17 is the main controller and low voltage is not required by other components except the PIC12/16/17. In these instances, the cost of the transformer becomes the sizable cost factor in the system. Trans¬formerless power supplies, thus, have a distinct advan¬tage
  • Transformerless Power Supplies: Resistive and Capacitive
    There are several ways to convert an AC voltage at a wall receptacle into the DC voltage required by a microcontroller. Traditionally, this has been done with a transformer and rectifier circuit. There are also switching power supply solutions, however, in applications that involve providing a DC
  • Power Distribution Units Branch Circuit Functions and Protection
    In the interest of saving space and reducing costs, some designers of power distribution/power controllers select fuses as opposed to electro-magnetic circuit breakers as a method of circuit protection. While there is little dispute that fuses can be substituted as over-current protection devices
  • Design A Load Sharing System Power Path Management with Microchip's Stand-Alone Li-Ion Battery Charger
    . They play an important consume energy directly from an ac-dc wall adapter or role in a person's daily life from every day tasks to accessory power adapter (or "Auto Adapter") when the entertainment. With the emerging technologies that are battery is low or the device is in a stationary mode
  • Power Supply Specifications and Replacement Circuit
    The purpose of this design is to use the BM1R001xxF series of secondary-side synchronous rectifying controller ICs to perform synchronous rectification in an AC/DC converter that uses diode rectification.
  • Reference Guide: Glossary of Terms
    AC Motor - AC Motors may be operated at a constant speed, without variable speed control, or may be furnished with a variable frequency controller for variable speed control. Variable speed AC Motors generally provide a 10:1 drive turndown ratio, typically for powering a feeder.
  • Understanding Variable Frequency Drives and Applications
    Variable frequency drives (VFDs) are solid-state electronic motor controllers that efficiently meet varying process requirements by adjusting the frequency and voltage of power supplied to an alternating current (AC) motor, enabling it to operate over a wide speed range.
  • Offline UPS Reference Design Using the dsPIC DSC (.pdf)
    The reference design in this application note describes the design of an Offline Uninterruptible Power Supply (UPS) using a Switch Mode Power Supply (SMPS) dsPIC (R) Digital Signal Controller (DSC). The Offline UPS Reference Design consists of three major UPS topology blocks: 1)Push-Pull Converter
