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
El principio de funcionamiento de una fuente de alimentación regulada se basa en un mecanismo de retroalimentación negativa. Cuando la tensión de entrada o la carga cambian, la tensión de salida fluctúa en consecuencia. En este punto, el circuito de retroalimentación recoge la señal de fluctuación de la tensión de salida y la envía al circuito de comparación. Este circuito compara la señal de retroalimentación con la tensión de referencia y genera una señal de error. Tras la amplificación, esta señal de error se envía al terminal de control del circuito de salida para ajustar las resistencias ajustables u otros componentes del circuito de salida, modificando así la tensión de salida y restableciéndola a un valor estable.
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.
