Types of IGCT devices IGCT (Integrated Gate-Commutated Thyristor) is a popular power semiconductor device used in medium and high voltage power electronic applications. The switch has outstanding capabilities as explained in [1] and [2]. In this post we will introduce three fundamental types of IGCT devices. IGCT device basically consists Read more…
How does DTC contribute to superior energy efficiency? Direct Torque Control (DTC) is well-known for its superior dynamic performance. Therefore, it is successfully used in applications requiring rapid change of torque in the range of few milliseconds. However, DTC has something to offer for less dynamic applications as well. In Read more…
IGBT versus IGCT power semiconductors – A brief comparison Semiconductor is the heart of any power electronic equipment. In medium voltage range of variable frequency drives two types of power semiconductors emerged: Insulated Gate Bipolar Transistor (IGBT) and Integrated Gate-Commutated Thyristor (IGCT). Naturally, there are many (white)papers, articles and presentations Read more…
