1. Full Wave Rectifier

실험1에서는 Full Wave Rectifier 회로를 구현하고 다양한 부하 조건에서의 출력 특성을 관찰하였습니다. 입력 신호가 모두 (+)로 정류되어 출력되는 것을 확인하였고, 부하에 커패시터를 연결할수록 DC 전압에 가까운 출력 파형을 얻을 수 있었습니다. 이론값과 실험값, 시뮬레이션 결과를 비교하여 오차 발생 원인을 분석하였습니다.
2. Buck Converter

실험2에서는 Buck Converter 회로를 구현하고 스위칭 주파수와 듀티 사이클 변화에 따른 출력 특성을 관찰하였습니다. 주파수가 높아질수록 오차율이 감소하는 경향을 보였고, 듀티 사이클이 작을 때 큰 오차가 발생하였습니다. 이는 고주파 구동 시 발생하는 왜곡과 듀티 사이클 제어의 정확성 문제 때문인 것으로 분석되었습니다.

1. Full Wave Rectifier

Full wave rectifiers are an essential component in power electronics, converting alternating current (AC) into direct current (DC). They are widely used in various applications, such as power supplies, battery chargers, and motor drives. The key advantage of a full wave rectifier is its ability to utilize both the positive and negative half-cycles of the AC waveform, resulting in a more efficient conversion process compared to half-wave rectifiers. This efficiency improvement is particularly important in applications where power consumption and energy efficiency are critical factors. Full wave rectifiers can be implemented using various circuit topologies, including the classic bridge rectifier and the center-tapped transformer configuration. Each topology has its own advantages and trade-offs, such as cost, complexity, and performance characteristics. The selection of the appropriate full wave rectifier circuit depends on the specific requirements of the application, such as the input voltage, output current, and desired level of ripple in the output. Overall, full wave rectifiers play a crucial role in modern power electronics, enabling the conversion of AC to DC in a reliable and efficient manner.
2. Buck Converter

The buck converter is a widely used power conversion topology in various electronic devices and systems. It is a type of step-down DC-DC converter that efficiently transforms a higher input voltage to a lower output voltage. The key advantage of the buck converter is its ability to regulate the output voltage while maintaining high efficiency, making it a popular choice for applications such as power supplies, motor drives, and battery-powered devices. The buck converter operates by using a switching mechanism, typically a transistor, to control the flow of energy from the input to the output. By modulating the duty cycle of the switching signal, the converter can adjust the output voltage to the desired level. The use of an inductor and capacitor in the output stage helps to smooth the output voltage and reduce ripple. Additionally, buck converters can be designed with various control schemes, such as voltage mode control or current mode control, to optimize performance and stability. The flexibility and efficiency of buck converters have made them an essential component in modern power electronics, enabling the development of compact, energy-efficient, and high-performance electronic systems.
