AC to DC Converter: Working Principle, Types, and Applications

Power Electronics

Introduction An crucial electronic device that transforms alternating current (AC) into direct current (DC) is an AC to DC converter, sometimes referred to as a rectifier. Power outlets typically supply AC electricity, but the majority of electronic devices—from smartphones to industrial machinery—run on DC power. From LED lights and battery charging to electric cars and […]

Power Electronics

What is an SCR (Silicon-Controlled Rectifier)? A four-layer semiconductor device called a silicon controlled rectifier (SCR) controls the flow of electrical power by acting as a switch. SCRs are within the category of thyristors, which are semiconductor devices used in alternating current (AC) circuits to regulate power. SCRs are crucial for applications requiring precise control

What is IGBT? working principle, types, construction, applications

Power Electronics

What is IGBT (Insulated Gate Bipolar Transistor)? An IGBT, or insulated gate bipolar transistor, is a three-terminal semiconductor device that is primarily used as an electronic switch. It combines the simple gate drive characteristics of a MOSFET with the high current and low saturation voltage capabilities of a BJT (bipolar junction transistor). This makes it
