    PMOS는 P형 반도체를 사용하여 Drain과 Source를 구성한다. Gate에 (-) 전압을 연결하면 Drain과 Source 사이에 Channel이 형성되어 그 사이로 전류가 흐른다. 이때 PMOS가 작동되도록 하는 기준 전압을 Threshold Voltage라 한다. 이렇듯 전기적인 조건에 따라 회로에 전류가 흐르는 여부가 결정되기 때문에 전기적 switch라고 부르는 것이다. 다만 이상적인 MOSFET은 위에서 살펴본 것과 같이 Threshold Voltage보다 낮은 전압이 인가되었을 때 회로에는 전류가 흐르지 않지만 우리가 사용하는 실제 PMOS는 미세하게 누설 전류가 흐른다. 또한 이상적인 MOSFET은 Threshold Voltage보다 높은 전압이 인가되었을 때 저항이 없는 short circuit과 같아지지만 우리가 실제로 실험에 사용하는 PMOS는 역시 약간의 저항이 생긴다.
    이번 실험에서 우리가 사용할 PMOS의 Data Sheet는 다음과 같다.

    • 1. Transformer
      Transformers are essential components in electrical power systems, playing a crucial role in the efficient transmission and distribution of electricity. They are used to step up or step down voltage levels, allowing for the effective transfer of power over long distances with minimal losses. The transformer's ability to convert alternating current (AC) voltages to different levels is fundamental to the operation of various electrical devices and power grids. Their versatility and reliability make them indispensable in a wide range of applications, from household appliances to industrial machinery and renewable energy systems. As technology advances, transformers continue to evolve, becoming more efficient, compact, and capable of handling increasingly complex power requirements. Understanding the principles and applications of transformers is crucial for engineers and technicians working in the electrical and electronics fields.
    • 2. Diode
      Diodes are essential semiconductor devices that play a crucial role in modern electronics. They are primarily used for the rectification of alternating current (AC) to direct current (DC), a process that is fundamental to the operation of power supplies, electronic circuits, and many other electronic systems. Diodes exhibit the unique property of allowing current to flow in only one direction, making them invaluable for tasks such as voltage regulation, signal detection, and protection against reverse polarity. As technology has advanced, diodes have become increasingly diverse, with a wide range of specialized types, including light-emitting diodes (LEDs), Zener diodes, and photodiodes, each serving specific applications. The continued development of diode technology has enabled the creation of more efficient, compact, and versatile electronic devices, contributing to the rapid progress of the electronics industry. Understanding the principles and applications of diodes is essential for engineers and technicians working in the field of electronics.
    • 3. Full wave rectifier
      The full-wave rectifier is a crucial circuit component that plays a vital role in the conversion of alternating current (AC) to direct current (DC). By utilizing a bridge of diodes or other semiconductor devices, the full-wave rectifier is able to convert both the positive and negative half-cycles of the AC waveform into a unidirectional DC output. This process is essential for powering a wide range of electronic devices, from household appliances to industrial equipment, as well as for charging batteries and other energy storage systems. The full-wave rectifier's ability to provide a more stable and efficient DC output, compared to its half-wave counterpart, has made it a widely adopted solution in power electronics and power supply design. As technology continues to evolve, the full-wave rectifier remains a fundamental building block in the development of increasingly sophisticated and energy-efficient electronic systems. Understanding the principles and applications of full-wave rectifiers is crucial for engineers and technicians working in the fields of power electronics and electrical engineering.
    • 4. Buck Converter
      The buck converter is a highly versatile and efficient DC-DC power conversion circuit that is widely used in a variety of electronic applications. By utilizing a switching mechanism and an inductor, the buck converter is able to step down a higher input voltage to a lower, regulated output voltage. This capability is essential for powering various electronic devices, from portable electronics to industrial equipment, where a stable and efficient power supply is required. The buck converter's ability to maintain a constant output voltage, even with fluctuations in the input voltage or load, makes it a crucial component in power management systems. As technology advances, buck converters have become increasingly sophisticated, with the incorporation of advanced control algorithms and integrated circuits, enabling even greater efficiency, power density, and reliability. Understanding the principles and design of buck converters is essential for engineers and technicians working in the fields of power electronics, power management, and electrical engineering.
    • 5. Buck-Boost Converter
      The buck-boost converter is a versatile power conversion circuit that can step up or step down a DC voltage, making it a valuable tool in a wide range of electronic applications. By utilizing a combination of switching mechanisms and energy storage components, the buck-boost converter can provide a regulated output voltage that is either higher or lower than the input voltage. This flexibility is particularly useful in scenarios where the input voltage may fluctuate or be unpredictable, such as in renewable energy systems, battery-powered devices, or automotive electronics. The ability to both increase and decrease voltage levels allows the buck-boost converter to adapt to various power requirements, enabling efficient and reliable power management. As technology advances, buck-boost converters are becoming more sophisticated, with improved control algorithms, increased power density, and enhanced efficiency. Understanding the principles and design of buck-boost converters is crucial for engineers and technicians working in the fields of power electronics, energy systems, and electrical engineering.
    • 6. Switch
      Switches are fundamental components in electrical and electronic systems, enabling the control and manipulation of electrical signals and power. They play a crucial role in a wide range of applications, from simple on/off control of household appliances to complex power management and signal routing in industrial and commercial systems. Switches come in various forms, including mechanical, solid-state, and electromechanical, each with its own unique characteristics and applications. The ability to selectively connect or disconnect electrical circuits is essential for tasks such as circuit protection, load control, and signal processing. As technology advances, switches are becoming increasingly sophisticated, with features like higher switching speeds, improved reliability, and enhanced energy efficiency. Understanding the principles, characteristics, and applications of switches is crucial for engineers and technicians working in the fields of electrical, electronic, and control systems design.
