稳压器的基本原理是通过负反馈控制，对输入电压进行采样、比较和调整，自动调整线圈匝数比或改变开关电源的占空比等，从而保持输出电压的稳定。以下是其具体介绍： 组成部分 稳压器通常由调压电路、整流电路、滤波电路、控制电路及伺服电机等组成。 工作过程 不同类型稳压器原理

A photovoltaic inverter is a device used to convert the direct current generated by photovoltaic panels (solar panels) into alternating current. Photovoltaic panels can convert sunlight into direct current, while photovoltaic inverters convert this direct current into the alternating current we use in our daily lives for use in households, industries, and businesses.The main functions

According to the data released in the first half of 2023, it can be seen that the power generation patterns of different technology types of components in 2023 are consistent with the same period last year. In 2023, TOPCon and IBC were 1.2% and 0.75% higher than PERC, respectively. In 2022, TOPCon and IBC were

The power supply time of UPS uninterrupted power supply is not infinite, and this time is influenced by factors such as the size of the battery’s stored energy, load size, environmental temperature, and battery discharge cut-off voltage. Generally speaking, the UPS uninterrupted power supply for small household computers can last for about 20 minutes. Large

UPS power supply can be divided into two categories based on its working mode: backup and online. According to its output waveform, it can also be divided into two types: square wave output and sine wave output. When the backup UPS power supply is in normal power supply, the mains supply directly provides power to

In the power guarantee system, the external battery pack of UPS (uninterruptible power supply) plays a crucial role. It can quickly provide power in the event of a power outage, ensuring the continuous operation of critical equipment. However, regular maintenance is essential to ensure that the battery pack is always in good working condition. The

Uninterruptible Power Supply (UPS) plays a crucial role in modern society, especially in ensuring that critical equipment and systems can continue to operate in the event of power fluctuations or interruptions. Next, this article will delve into the definition and functions, working principles, and wide range of application scenarios of UPS.1、 Definition and FunctionContinuous power

The UPS battery room should be equipped with a gas fire extinguishing system or a fine water mist fire extinguishing system. When using a pipeline gas fire extinguishing system, the battery room should be equipped with two independent fire detectors at the same time, and the fire alarm system should be linked with the fire
