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
稳压电源的工作原理基于负反馈机制。当输入电压或负载发生变化时，输出电压会随之波动。此时，反馈电路会采集输出电压的波动信号，并将其送入比较电路进行比较。比较电路将反馈信号与参考电压进行比较，产生一个误差信号。该误差信号经放大后送至输出电路的控制端，调节输出电路中的可调电阻或其他元件，从而改变输出电压并使其恢复到稳定值。
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.
