Understanding MOSFET Avalanche Rating, Testing and Protection
In this post we discuss MOSFET avalanche ratings, and learn how to understand this rating in the datasheet correctly, how the parameter is tested by the manufacturer, and measures to […]
What is IGBT: Working, Switching Characteristics, SOA, Gate Resistor, Formulas
IGBT stands for Insulated-gate-Bipolar-Transistor, a power semiconductor which includes the features of a MOSFET’s high speed, voltage dependent gate switching, and the minimal ON resistance (low saturation voltage) properties of […]
Ceiling LED Lamp Driver Circuit
Nowadays the CFL and fluorescent lamps are almost completely replaced with LED lamps, which are mostly in the form of circular or square shaped flat ceiling mounted LED lamps. These […]
