突然停电，你会失去工作，这很烦人。虽然停电有所减少，但拥有UPS 或 逆变器(Inverter)仍然是一个好主意。我正在为那些对是否应该为他们的计算机和电子设备购买UPS或逆变器感到困惑的人写这篇文章。(Inverter)这些设备具有时间敏感性，切换电源时的差异不应超过 3-4 毫秒，否则它们将关闭。在这篇文章中，我将分享UPS(UPS)和逆变器(Inverters)之间的区别。
什么是 UPS？
UPS或不间断电源(Power Supply)装置在断电时继续为连接的设备供电。UPS具有最快或接近于零的切换时间，因为它们持续使用电池电源运行并同时为电池充电。这种安排可确保连接的设备在断电时不会关闭。
什么是逆变器？
逆变器旨在为风扇和灯等家用电器供电。它们直接在市电中运行，直到断电，然后在几微秒内切换到电池电源，这比UPS切换时间还长。
UPS与逆变器的区别
我们不会深入探讨这些设备的内部工作机制，而只会涉及最终用户可能感兴趣的因素。
1]用例和备份时间(1] Use Case & Backup Time)
如果您不经常断电，您可以使用UPS来保护您的计算机免受任何重大硬件故障的影响。切换到UPS几乎是即时的，这不会关闭您的计算机。UPS通常提供大约 30 分钟左右的备份。
UPS从市电到电池的切换是立即的，而逆变器(Inverter)则比UPS需要更多。对于电脑来说，逆变器的开关时间超过了它所能承受的范围，通常会因为供电中断而重启。因此，UPS是 PC 的首选，逆变器(Inverter)是家庭的首选，因为灯泡不会关心开关延迟。
UPS可以为您的设备提供大约 15 分钟的备份，而逆变器(Inverter)可以根据其容量提供几个小时的备份。逆变器允许您根据容量为整个房屋供电。因此，如果您所在地区的停电时间更长，您可以使用它至少保持几个灯和风扇运行。

2] 维护和使用寿命(2] Maintenance & Lifespan)
UPS 是免维护的。逆变器需要更多的接线，并且需要定期注入蒸馏水。然而，我注意到一些高级版本的逆变器已经将消费者从蒸馏水维护中解放出来。
UPS的缺点是即使没有停电，电池也会不断地充电和放电。正因为如此，电池的损耗比逆变器电池快4-5倍。
3] 价格(3] Price)
与逆变器相比，UPS更便宜。有不同类型的UPS和逆变器可供选择，并且价格具有竞争力。
购买它们时要考虑的因素包括备用时间、容量、充电时间、功率要求、板条箱（充满电的电池中的充电量）和保修。
您应该为计算机和类似设备购买UPS还是逆变器？(Inverter)
既然你已经清楚了UPS(UPS)和Inverter之间的区别，那么我们来总结一下你的电脑需要哪一个。
逆变器不用于计算机，因为切换时间太长，无法处理。有时(Sometimes)家用逆变器确实适用于 PC。如果你有与家用逆变器兼容的金牌电脑电源，但它对PC组件的压力更大。
因此，如果您对是否需要为您的计算机购买UPS或逆变器(Inverter)感到困惑，答案是直截了当的。买个UPS。
我希望这可以澄清差异。(I hope this clarifies the differences.)

Difference between UPS & Inverter - Which is better?
It’s annoying when the power goes out all of a sudden, and you lose work. While power cυts havе reduced, having a UPS or Inverter is still a good idea. I am writing this post for those who are confused if they should buy a UPS or Inverter for their computer and electric devices. These devices are time-sensitive, and there should not be more than 3-4 milliseconds difference when switching power else they will shut down. In this post, I will share the differences between UPS and Inverters.
What is a UPS?
UPS or Uninterruptible Power Supply unit continues to supply power to the connected device when there is a power cut. UPS have the fastest or close to zero switching time since they continuously run on the battery power and charge the battery simultaneously. This arrangement makes sure that the connected devices don’t shut down when the power goes out.
What is an Inverter?
Inverters are meant to power household appliances like fans and light. They run directly in mains power till there’s a power cut and then switch to battery power in a few microseconds which are more than UPS switching time.
Difference between UPS & Inverter
We are not going into the internal working mechanism of these devices but only touching upon the factors which may interest the end-user.
1] Use Case & Backup Time
If you don’t have power cuts often, you can use a UPS to safeguard your computer from any major hardware failure. The switch to UPS is almost instant, and this doesn’t shut down your computer. UPS typically offers a backup of around 30 minutes or so.
The switching of UPS from the mains supply to the battery is immediate, whereas the Inverter takes more than UPS. For computers, the switching time of inverter is more than it can handle, and it will usually reboot due to the interrupted supply. Thus, UPS are preferred for PC and Inverter for homes as lightbulbs will not care about the switching delay.
UPS can provide backup for your devices for around 15 minutes, whereas an Inverter can provide backup for hours depending on its capacity. The inverter allows you to power the complete house depending on the capacity. So if your area has a more extended power cut, you can use it at least keep a couple of lights and fan running.

2] Maintenance & Lifespan
UPS are maintenance-free. Inverters need more wiring and need to be filled with distilled water at regular intervals. However, I have noticed that some of the advanced versions of inverters have freed consumers from distilled water maintenance.
The disadvantage of UPS is that since the battery is continuously being charged and discharged even when there’s no power cut. Because of this, the battery will wear out 4-5 times quicker than inverter battery.
3] Price
Compared to Inverters, UPS are cheaper. There are different types of UPS and inverters available, and they are available at competing prices.
The factors to look into when buying them includes backup time, capacity, charging time, power requirement, crating (quantity of charge in a fully charged cell), and warranties.
Should you buy a UPS or Inverter for the computer and similar devices?
Now that you are clear about the difference between UPS and Inverter, let’s summarize which one you need for the computer.
Inverters aren’t used for computers as the switching time is too much for them to handle. Sometimes home inverters do work for PC. If you have gold-rated computer power supply which is compatible with the home inverter, but it puts more stress on the PC components.
So if you are confused if you need to buy UPS or Inverter for your computer, the answer is straight forward. Buy a UPS.
I hope this clarifies the differences.
