As a power supply device that converts AC voltage into stable DC voltage, a regulated power supply plays an indispensable role in many fields. Next, we will delve into what a regulated power supply is? What are the types of regulated power supplies (www.szsger. com).
1. What is a stabilized power supply
A regulated power supply, as the name suggests, is a power supply device that can stabilize the output voltage. When the power supply voltage fluctuates or the load changes, it can automatically adjust the output voltage to maintain it within the set value range, thereby ensuring the stable operation of the equipment.
2. Working principle of stabilized power supply
레귤레이터 전원 공급 장치의 작동 원리는 음의 피드백 메커니즘에 기반합니다. 입력 전압이나 부하가 변하면 출력 전압도 그에 따라 변동합니다. 이때 피드백 회로는 출력 전압의 변동 신호를 수집하여 비교 회로로 전송합니다. 비교 회로는 피드백 신호를 기준 전압과 비교하여 오차 신호를 생성합니다. 이 오차 신호는 증폭 후 출력 회로의 제어 단자로 전송되어 출력 회로의 가변 저항이나 기타 부품을 조정하여 출력 전압을 변경하고 안정적인 값으로 복원합니다.
What are the types of regulated power supplies
Linear regulated power supply: This is a common type of regulated power supply, whose basic principle is to reduce the input power supply voltage to the required output voltage, and then stabilize the output voltage through components such as resistors, capacitors, and linear regulators.
Application scenario: Suitable for laboratory instruments, precision measuring equipment, and other situations that require high power stability.
Switching stabilized power supply: This type of power supply controls the output voltage through a switch tube switch. The basic principle is to convert the input power supply voltage into high-frequency AC power, and then filter and stabilize it through magnetic components and switch tubes, ultimately outputting a stable DC voltage.
Application scenarios: Widely used in fields such as computers, communication equipment, household appliances, etc., it meets the needs of various electronic devices for efficient and stable power supply.
AC voltage regulator: also known as AC voltage regulator, commonly includes ferromagnetic resonant AC voltage regulator, magnetic amplifier AC voltage regulator, sliding AC voltage regulator, inductive AC voltage regulator, and thyristor AC voltage regulator. These voltage regulators stabilize the output voltage through different principles.
Application scenarios: Widely used in industrial automation equipment, communication equipment, medical equipment, laboratory instruments, and household appliances to ensure stable operation of the equipment.
In summary, regulated power supplies are an indispensable part of electronic devices, with diverse types and wide application scenarios. With the continuous development of technology, the performance of regulated power supplies will continue to improve, providing more stable and efficient power supply guarantees for various electronic devices.
