Effects of Humidity on Power Electronics Design
Air humidity is likely to condense at all parts of a device if the device temperature differs from the air temperature to a certain extent. In extreme cases, condensation causes the...
View ArticleModeling of Temperature Dependence of Power Semiconductor I-V Curves
The I-V curve is the most important parameter of power semiconductors (PSD), since power semiconductor output capacity and efficiency depends upon it to a great extent. Many publications...
View ArticleLoss Reduction in Power Electronics Switches by Soft Switching
Soft switching is a possible way of reducing losses in power electronic switches. The expression "soft switching" actually refers to the operation of power electronic switches as...
View ArticleFault Current Detection and Reduction in Converter Circuits
Errors in converter circuits may be detected at various points. The responses to detected errors, however, may be very different. The term fast protection is used if an error signal is...
View ArticleOvervoltage Limitation for Power Transistors
Overvoltage limitation between main terminals Measures to limit overvoltages between main terminals (collector-emitter voltage, DC link voltage) can be divided into passive snubber...
View Article62mm Modules Application and Assembly Notes
Important aspects in the construction of the mechanical layout include the application conditions at which the components are put to use. These application conditions must be observed in...
