The key task of the UPS is to ensure that the power supplied to the IT equipment meets the specific requirements of the equipment power supply under various input and communication conditions (including generator operation). Now let's see how different designs meet the following main criteria:

Ÿ Keep the voltage within the allowable range

转换 Convert between modes without locking IT equipment

平滑 Smooth transition between generator and generator

Impact of UPS topology on performance:
Maintain the voltage within the allowable range

The UPS output voltage must be within the acceptable tolerance of the ITIC voltage tolerance curve specified by the Information Technology Industry Council (ITIC) for all input AC line conditions.

The vertical axis shows the input voltage of the power supply unit (PSU). The horizontal axis represents the time at which the input voltage is problematic (up to 10,000 AC cycles, approximately 28 minutes). The ITIC curve (which is more like a ladder than a curve) shows an acceptable input voltage envelope for a typical power supply unit (PSU) design for IT equipment.

The UPS must ensure that the voltage input to the power supply unit (PSU) is not within the forbidden range above the acceptable range because voltages within this range can damage the IT equipment. A voltage below the threshold can cause the power supply unit (PSU) to shut down or abnormal behavior.
