SMPS 和 UPS 的区别

1. 开关电源(SMPS)：
它用于从一个特定的直流电压改变到另一个直流电压电平，通常它将电源电压降低到一个较低的电平，以便它可以被需要较低电压的组件使用。

2. 不间断电源(UPS)：
它用于在固定的时间内为设备供电，即使在没有输入电源的情况下也不会停止。

SMPS 和 UPS 的区别：

Parameter	UPS	SMPS
Power Conversion	Provides A.C supply when power fails.	Converts A.C to D.C power.
Transformers Used	Low-frequency transformers used.	High-frequency transformers used.
Backup	UPS have backup capabilities.	SMPS don’t have any kind of backup capability.
Power Storage	Power storage equipment is used to store the incoming supply.	No power storage equipment used.
Pricing	It is usually costlier than SMPS.	Prices are usually lower than UPS.
Placement	Usually outside the cabinet.	Inside the cabinet.
Size	Usually, the size is slightly bigger than SMPS.	Usually, Smaller than UPS.
Electronic Components	Rectifier, UPS Batteries, Inverter, Static Bypass Switch.	PWM Oscillator, HF rectifier, MOSFET switch.
