Insulated gate bipolar transistor (igbt) - basics
An insulated-gate bipolar transistor (IGBT) is a three-terminal semiconductor device that combines high efficiency and fast switching. It consists of alternating P-N-P-N layers controlled by a metal-oxide-semiconductor (MOS) gate structure, without regenerative action. The IGBT structure is similar to a thyristor with an isolated MOS gate that completely suppresses the thyristor action. IGBTs are used in switching power supplies for applications requiring high power, such as variable frequency drives, electric vehicles, and air conditioners. The IGBT combines the simple gate drive of MOSFETs with the high-current and low-saturation-voltage capabilities of bipolar transistors.

Advanced control scheme of doubly fed induction generator for wind turbine us...
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
