IGBT:
Insulated Gate Bipolar Transistor. is a three-terminal
Power
semiconductor device that combines the simple gate
drive characteristics of the
MOSFETs with the high current and low saturation
voltage capability of bipolar
transistors by combining an isolated gate
FET for the control input, and a bipolar power
transistor as a switch, in a single device.

I/O Port:
("Input and Output port") A bidirectional pins in a
device or chip to exchange data with other devices
and/or world.
|
|
Impedance:
Represented by the symbol Z, is a measure of the
opposition to electrical flow. It is measured in
ohms.
|
|
Inductive Kickback:
The very rapid change in voltage across an inductor
when current flow is interrupted.
Snubber diodes are often used to channel this
energy in relays, and other inductive loads. Kickback
can be a problem (causing EMI and component failure);
or it can be used in
power supply
circuits to develop higher or opposite-polarity
voltages from a single supply.

Inertia:
A property of matter that causes it to resist changes
in speed or direction. |
|
Inverting
Switching Regulator:
A switch-mode
voltage regulator in which output voltage is
negative with respect to its input voltage.

|
IR Infrared:
Light that has a frequency below the visible light
spectrum used for remote controls, line-of-sight
wireless data, and night vision applications, among
others.
