2.2 Working Principle

2.2.1 Conceptual Diagram

The UPS5000 is an online product. It uses a modular design, which facilitates
maintenance and capacity expansion. The UPS5000 uses the digital signal
processing (DSP) technology for intelligent control. Its power module consists of a
rectifier, inverter, and DC/DC converter. The UPS5000 converts inputs into pure
high-quality sine wave outputs by using the high-frequency switching technology.

2.2.2 Working Modes

2.2.2.1 Normal Mode

In normal mode, the rectifier converts AC power into DC power, then the inverter
converts DC power into high-precision AC outputs. The conversions protect loads
from interference such as input harmonics, glitches, and voltage transients.
