IGBT first of all is a hybrid device meaning the combination of two devices; the BJT and the MOSFET. Depending on the application, one can never say an IGBT is better than others. Typically, an IGBT is ideal for high powered, high voltage and high frequency applications
Yes
supposed to be MOSFET. but i also depends on your working freq.
Shorting the gate to the cathode in an IGBT (Insulated Gate Bipolar Transistor) can be done to quickly turn off the device and prevent it from conducting. This action helps to ensure that the IGBT is safely switched off during fault conditions or when a rapid shutdown is needed. It effectively discharges any gate capacitance, leading to a faster turn-off time and reducing the risk of damage from excessive current. However, this practice must be used with caution to avoid unintended consequences in the circuit operation.
A snubber circuit is typically connected across an IGBT (Insulated Gate Bipolar Transistor) to protect it from voltage transients and reduce voltage spikes during switching events. It usually consists of a resistor and a capacitor in series (RC snubber) or a diode-capacitor combination for diode snubbing. The snubber absorbs excessive energy, minimizing the risk of damage to the IGBT and improving overall performance by smoothing out the voltage waveform. Proper design of the snubber is crucial to effectively dampen oscillations and ensure reliable operation.

There are times when you just can not really protect some devices. IGBT's are serious power devices. Circuitry can sense over currents, but possibly not fast enough to save an IGBT. Over sizing them is probably your best bet.
Single means there is just one. Dual means there are two IGBT's (Insulated Gate Bipolar Transistor) inside the one package.
Renewable Energy and IGBT Inverters
IGBT and BJT are bipolar devices as the name suggest. Meaning of bipolar device both electrons and holes leads to current unlike FET where either electron or hole causes current.
