• 1. Switching Mode Power Supply (SMPS)

  SMPS (Switching Mode Power Supply)의 동작 원리와 회로 모듈을 이해하여 SMPS를 설계할 수 있는 능력을 배양한다. PWM 제어 회로는 출력 전압의 오차분에 상응하여 펄스폭을 조정하여 출력 전압을 안정화 시키는 회로이며 크게 세가지로 구성되어있다. 오차 증폭기(Error amp), 비교기(Comparator), 구동회로(driver stage)로 구성된다. 생성된 구형파 펄스는 UC3845의 6번 output 핀을 통해 구동회로의 스위치로 동작한다. Buck Converter 회로와 Boost Converter 회로를 이용하여 SMPS를 설계하는 방법이 설명되어 있다.

• 1. Switching Mode Power Supply (SMPS)

  Switching Mode Power Supply (SMPS) is a highly efficient and widely used power conversion technology that has revolutionized the way we power electronic devices. SMPS offers several advantages over traditional linear power supplies, including higher efficiency, smaller size and weight, and the ability to handle a wide range of input voltages. The key principle behind SMPS is the use of switching transistors to rapidly turn the power on and off, rather than continuously regulating the voltage like in a linear power supply. This switching action allows for more efficient power conversion, as the transistors spend less time in the linear region where power is dissipated as heat. SMPS also enables the use of smaller and lighter components, such as transformers and capacitors, which can be optimized for the high-frequency switching operation. One of the main benefits of SMPS is its high efficiency, which can reach up to 90% or more, depending on the design and application. This efficiency translates to reduced energy consumption and heat generation, making SMPS an attractive choice for a wide range of applications, from consumer electronics to industrial equipment. Another key advantage of SMPS is its ability to handle a wide range of input voltages. This flexibility allows SMPS-based power supplies to be used in various parts of the world, where the mains voltage can vary significantly. This makes SMPS-based power supplies highly versatile and adaptable to different environments. Despite these advantages, SMPS also come with some challenges, such as the generation of electromagnetic interference (EMI) and the need for careful design to ensure stable and reliable operation. However, with advancements in semiconductor technology and power electronics, these challenges are being addressed, and SMPS continue to be the preferred choice for power conversion in a wide range of applications. In conclusion, Switching Mode Power Supply (SMPS) is a highly efficient and versatile power conversion technology that has become an integral part of modern electronic devices and systems. Its ability to provide high-efficiency power conversion, compact size, and adaptability to different input voltages make it an essential component in the world of electronics and power management.
