In industry a common application is the variable speed drive (VSD) that is used to control an induction motor.

Servo motor controllers, where linearity is not important.

Often, there may arise the need to apply an AC PWM drive1 to input voltages such as 200, 208, 380, 415 and possibly other levels, as well as input frequencies such as 50 Hz. The AC PWM regulator utilizes a switching power supply for control power that is sourced from a DC bus. This gives the unit

, adjustable-frequency inverter that adjusts frequency and voltage to vary the speed of an otherwise fixed-speed AC motor. This control is typically produced through pulse width modulation (PWM) of the drive output to the motor. Voltage and frequency are maintained in a constant relationship at any

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

I am looking for detailed schematics for the control brd located inside the PIM of the ev1. The PIM is the box that uses 300Vdc input (from batteries/rectifier) and converts the DC into 3 phase variable frequency AC output, to run the main motor (inductive motor). I converts DC to AC by use of a 3 p...

Hello, I'm building a grid-tie inverter of my own. I have yet to prototype the unit but if the specs of the components I'm using on my design are any indicator, my unit shall have the following specs... Voltage = 120VAC Peak Apparent Power = 2400VA Peak Current = 20A Duty =...

DUBLIN--(BUSINESS WIRE)--Research and Markets (http://www.researchandmarkets.com/research/h2cqjb/global_ac_and_dc) has announced the addition of the "Global AC and DC Drives Market 2012-2016" report to their offering. One of the key factors contributing to this market growth is increasing demand for AC and DC drives from the APAC region. The Global AC and DC Drives market has also been witnessing increasing demand for end-to-end systems. However, continuous decline in vendors'' profit margin coul
