Proton Irradiation Technology
Control of recombination features in the layers of the semiconductor elements is considered to be one of the most effective methods of increasing performance and many other characteristics of power...
View ArticlePower Devices Produced Using Proton Irradiation Technology
The application of proton irradiation technology has made possible the production of a new series of fast thyristors. These semiconductors have remarkably small turn-off time, small recovered charge...
View ArticleThyristor Basics
A thyristor is a four-layered semiconductor rectifier that consists of alternating p-type and n-type materials (see "Semiconductor Doping") forming three P-N Junctions. For thyristors, the flow of...
View ArticleDynamic Properties of Thyristors
Thyristor triggering mechanisms The flow of current through a thyristor can result in several ways. Triggering mechanisms for thyristors include the following: Trigger current...
View ArticleHigh Voltage Thyristors Adjusted for Usage in Series Assemblies and Stacks
Despite significant development of converters on the basis of fully controlled semiconductor stacks (IGBT, GTO, IGCT), today it is still technically legitimate and acceptable to use “traditional”...
View ArticleHigh Voltage Power Thyristor with Built-in Protective Elements
Despite the possibility of “outer” protection, usage of thyristors with built-in elements for protection against excess voltage may also be attractive to customers if such a thyristor has the same...
View ArticleApplication Fields and Current Performance Limits for Power Semiconductors
The development of power semiconductors saw the onset of lasting success for power electronics across all fields of electrical engineering. Given the ever increasing call for resource conservation...
View ArticleMounting of Capsule Diodes and Thyristors (disc cells)
Disc cell housings possess two thermal contact surfaces. For maximum current capacity yields, double-sided cooling (DSC) is usually used. For this purpose, the cell is clamped between two heat sinks...
View ArticleSeries and Parallel Connection of Diodes and Thyristors
Parallel connection of thyristors In parallel thyristor circuit arrangements, homogenous current distribution is required from the moment of firing and throughout the entire current...
View ArticleStructure and Functional Principle of Thyristors
A thyristor is a semiconductor component with a minimum of three pn-junctions which can be switched from off-state to on-state. Often, "thyristor" specifically designates the...
View Article3% import tax for power electronics modules to China
Based on a recent publication (in Chinese) released on the 16th of December 2013, it seems that the Chinese government has introduced to its tariff policies a 3% customs duty for importing power...
