Examples of IGBT Use and Techniques IGBTs are used in a wide variety of applications including solar inverter, energy storage system, uninterruptible power supply (UPS), motor drives, electric vehicle charger and industrial welding as well as in domestic appliances.

What is the difference between power transistor and IGBT?

An IGBT (Insulated Gate Bipolar Transistor) is different from a power transistor in that it is controlled by the voltage applied to its gate rather than the current flowing into its base. The current flowing in the gate of an IGBT is extremely small because the impedance of the control gate is very high.

What is an IGBT in a solar inverter?

An IGBT (Insulated-Gate Bipolar Transistor) is a fast switching device used in solar inverters. It transforms electrical current from an AC line circuit to DC, or from DC to AC.

What types of inverters are used in photovoltaic applications?

This article introduces the architecture and types of inverters used in photovoltaic applications. Inverters used in photovoltaic applications are historically divided into two main categories: Standalone inverters are for the applications where the PV plant is not connected to the main energy distribution network.
