UPS Software Development Kit for Analog Devices ADMC401

The Ups Development Kit is a software tool intended to help the understanding and the development of a full digitally controlled on-line, single phase Uninterruptible Power Supplies using the ADMC401 single chip motor controller. It lets the developer exploit some important UPS control issues with the only aid of the ADMC401 Evaluation Board and Motion Control Debugger (Mcd). Following you can find usefull information about applications, technologies and tools that find home at Bluewind today.

A reference design

The so called double-conversion (on-line) UPS topology is taken as a reference to show ADMC401 control capabilities. Most kind of UPS topologies can easily reuse the software modules contained in the kit. A large set of ADMC401 peripherals is used, enabling the developer to startup with:

8 channel/12bits flash (2us) analog to digital converter
Event Timer Unit (ETU), which is the core of a fast Phase Locked Loop system
Parallel input/output programming and usage
Pulse Width Modulation unit programming and usage
Serial Port 0 programming and usage as a synchronous port at 6 Mbits/s

No hardware

No external hardware is required, except some simple wiring beween accessible points of the ADMC401 connector board.

Modularity

The software modules are mostly stand-alone, with a clear input-output interface, and all related variables are declared within each module. When needed, variables are declared visible to other modules by using include files technique. The package covers most of the UPS control and regulation issues:

Initialization and task manager (umain.dsp)
Input-output synchronization (pll.dsp)
Period, frequency and phase measurements (pll.dsp)
Mains monitoring (mains.dsp)
RMS and power measurements (measure.dsp)
Output waveform monitoring (bypass.dsp)
Inverter waveform regulation (vcontrol.dsp)

A living project

The current release (rel.1.0) deals with the most important UPS control topics. Still the software will be updated and enriched with an increasing number of modules and utilities, to cope with many more control issues.
