Dsp AC uninterruptible power supply

What is an uninterruptible power supply (UPS)?

An Uninterruptible Power Supply, or UPS, is an electronic device that provides an alternative electric power supply to connected electronic equipment when the primary power source is not available.

Why should you use a DSP engine & IPP?

The built-in DSP engine and IPP help in optimizing control loop design, being able to produce a clean sine wave output (THD less than 3%) even with a rectifier load and a crest factor of 3:1.

What is microchip dsPIC DSC?

The Microchip dsPIC DSC device provides all of the necessary power peripherals used for power conver-sion applications. It is a highly flexible Intelligent Power Peripheral (IPP), ADC, Comparator, and PWM mod-ules simplify the hardware schematic and reduces the number of components in the design of a high-perfor-mance UPS system.

What are the DSP instructions in dsPIC DSC?

The DSP instructions of the dsPIC DSC device are uti-lized to efficiently execute the RMS calculation rou-tines. The Q15 library includes functions for calculating sum-of-squares and square-root. Both of these opera-tions are available in the Q15 library, and are used for implementing the RMS calculation in the offline UPS reference design.
