UPS Circuit Board

When incoming power is interrupted, a computer can continue to function for at least a short while thanks to an uninterruptible power supply (UPS). Utility electricity replaces and preserves energy storage as long as it is available. A UPS varies from an auxiliary, emergency, or standby power system or standby generator in that it will supply energy from batteries to give almost immediate protection against input power interruptions.

Different Types Of UPS PCB

  • Standby UPS PCB: The offline UPS PCB is another name for this type of PCB, which is typically found in personal computers.
  • Standby UPS PCB: This kind of PCB, commonly known as the offline UPS PCB, is typically seen in personal computers.
  • Double Conversion Online UPS PCB: The most popular configuration for devices with a rating of more than 10kVA is this UPS PCB.


  1. Rectifier: It is the rectifier’s job to change the AC voltage into a DC voltage. Along with maintaining the float voltage of the device, it also charges up the UPS PCB’s storage batteries. While buffering any surge, it quickly manages any circuit overload. It is capable of handling a very broad range of input voltage fluctuations.
  2. Inverter: The inverter is a piece of technology that can convert the DC voltage from a lead acid battery to an increased DC voltage. Electrical noise, surges, and spikes are filtered out by the AC-DC-AC conversion process. The result is a clean sine waveform as the output.
  • Bypass: directly outputs the AC power
  1. Switch: A printed circuit that alternates between bypass output and inverter output
