Importance of Current Sensing in Power Supplies


Applications relying on power supply, utilizing devices composed of power electronics (chargers, DC links, batteries, inverters, and/or rectifiers) all require effective control, monitoring, regulation, and protection of current. This is essential to guarantee their integrity and proper operation. In numerous applications, the grid voltage is either excessively high or needs conversion to DC voltage or a distinct AC waveform. Modern power electronics play a pivotal role in transforming this voltage. Current sensors play a crucial role in measuring the output current, ensuring a stable power supply.


Typical Applications in Power Supplies


The indispensable role of power supply in ensuring the efficient operation of critical applications like cell phone base stations or hospital security systems, which must maintain constant functionality. In the event of a failure (such as a short circuit, unexpected grounding, etc.) or a grid fault causing a power interruption, batteries or Uninterruptible Power Supplies (UPS) step in to offer temporary emergency power. Current sensors play a pivotal role in overseeing the charging and discharging processes of these batteries, as well as managing the switch to activate the batteries and UPS.


Uninterruptible Power Supplies (UPS)

To be more specific on UPS, an UPS is a crucial device in various industries and settings, designed to provide emergency power to a load when the main power source fails. Here are some common applications of UPS systems:

1.Computers and IT Equipment


3.Medical Equipment

4.Industrial Automation

5.Emergency Services

6.Retail and Point of Sale (POS) Systems

7.Security Systems

8.Network Infrastructure

9.Home and Small Office

10.Educational Institutions


The primary goal of a UPS is to provide a temporary power source during electrical outages or fluctuations, allowing connected devices and systems to shut down gracefully or continue operating until normal power is restored. UPS systems come in various sizes and types to meet the specific needs of different applications.
