UPS/Inverter is an electronic device that provides backup power during power outages or fluctuations.
UPS stands for Uninterruptible Power Supply while Inverter converts DC power to AC power.
UPS provides instant backup power during power outages while Inverter provides backup power after a few seconds of power outage.
UPS is commonly used for computers, servers, and other critical equipment while Inverter is commonly use...
IGBT/MOSFET are types of transistors used in power electronics.
IGBT stands for Insulated Gate Bipolar Transistor and is used for high voltage and high current applications.
MOSFET stands for Metal Oxide Semiconductor Field Effect Transistor and is used for low voltage and low current applications.
Both IGBT and MOSFET are used as switches in power electronics.
IGBT has a higher switching speed than MOSFET but MOSFET has a...
The basic component of electronics is the resistor, capacitor, and inductor.
Resistor: limits current flow
Capacitor: stores electrical charge
Inductor: stores electrical energy in a magnetic field
Diode: allows current to flow in one direction
Transistor: amplifies or switches electronic signals
Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.
Transformers work on the principle of electromagnetic induction
They consist of two coils, primary and secondary, wound around a magnetic core
When an alternating current flows through the primary coil, it creates a magnetic field that induces a voltage in the secondary coil
This voltage can be stepped up...
