Transistors
Transistors are semiconductor electronic components used for signal amplification, current switching, and controlling other circuits. They are fundamental components of integrated circuits and logic circuits.
Types of Transistors:
1. Bipolar Junction Transistors (BJT)
- Consist of three semiconductor layers (NPN or PNP).
- Operate by controlling the base current, which regulates a larger current flow between the collector and the emitter.
- Used in audio amplifiers, logic circuits, and power controllers.
2. Insulated Gate Bipolar Transistors (IGBT)
- Combine the advantages of MOSFET and BJT transistors, offering high efficiency and high conduction currents.
- Used in power converters, inverters, and high-power motor controllers.
3. Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFET)
- Operate based on an electric field that controls the current flow between the drain and the source.
- Include N-channel and P-channel MOSFETs, which are widely used in digital electronics and power electronics.
- Commonly found in switching power supplies, digital circuits, and motor control systems.
Applications of Transistors
