Advantages of Implementing DSP Technology
Crowded data centers and racks filled from top to bottom with storage devices, monitors, servers, communications devices and other equipment are driving the need for UPS technology with increased power efficiency, within a compact and sleek form factor.
For end-users and facilities managers, ‘thin is in’, and so UPS designers continually strive for smaller products, fewer parts, lower cost and less weight. Even implementation of DSP technology in Home UPS (INVERTERS) is quite popular.
Digital signal processor (DSP) controllers are an enabling technology for meeting the challenge of such design requirements. DSPs are now propelling forward many of the advances in UPS design.
DSP controller manages many UPS functions including:
- Sensing and controlling input and output voltage and current levels
- Setting and controlling the rectifier (a boost converter) for input power factor correction and for
regulating the DC voltage into the inverter. - Setting and controlling the inverter (a buck converter) for output voltage and frequency regulation
- Controlling the battery charger
- Interfacing with power management software through communication port cards
- Switching to electronic bypass
