    Recommended MOSFET Gate Driver and MOSFETs for H-Bridge Motor Controller

    Evening gents, I'm trying to pick out MOSFETs along with a MOSFET Gate Driver from International Rectifier that will suit my needs. (See http://www.irf.com/indexsw.html) The MOSFETS will be used in an H-Bridge configuration, with the MOSFET Gate Driver driving the gates of each respective...

    Motor Controller - Understanding the circuitry external to the ICs

    Evening gents, Attached is schematic of a motor controller I am looking to modify and implement. As a start, I've been reading through the datasheets of the IC's and began looking the the external resistors and capacitors to try and figure how the particular R and C values were selected. 1)I...

    0-30V Stabilized Power Supply

    Hello, I'm looking to build my own lab power supply, but am still fairly new to the "practical" aspects of electronics.(i.e. wiring circuits up to mains voltages) I've taken two university level courses on electronics, but I still feel I have a lot to learn. (Currently reading "The Art of...

    Buck Converter Design Problem

    See attached figure for design requirements. I decided to experiment, solving the outcomes of L, C, ΔiL, IL and R given a selected frequency, input voltage and output voltage. Of course to obtain the values of the outcomes in a simple manner I made various assumptions. These assumptions are...

    What is a Reactor? (Context: Substations)

    Is that it's main application? I've also read that is used for stabilizing when a short occurs.

    What is a Reactor? (Context: Substations)

    As the title so bluntly states, what's the purpose of a Reactor? I'm an engineering student and the group I'm currently working for does lots of consulting work for a number substations and what I've often seen in the project descriptions is things like, "Reactor Salvage & Replacement", but...
