Dear Sirs.

We, Mareton d.o.o. firm, Croatia, Zagreb deals with power electronics devices productions and developing of same; power sources, ups, etc. I’m a senior engineer for a new generation of inverters in ups. I’d like to ask you for some help.

Technical data:

UPS, double conversion topology dc-dc-ac, power of unit S=3kVA, cosφ >0.8, output grid, single phase, 230V-50Hz, control bypass device. Input, dc 24V, 48V, 110V, 220V battery. For each battery another dc-dc type. While inverter is the same for any type.

Special requests; parallel operation, or single inverter which has to operate synchronized with the grid, and others inverters autonomy (has own protections, on-off switching, and can activate well-defined fuses in itself branch... so it has no output current limit but the components are dimensioned to keep the short circuit branch current). The number of parallel “Lego parts” is not limited, which has to be able to increase the power capacity of ups output. But the service is equal, unique inverter, and service components.

We have in testing, with expected results, models realized with adequate power components, and control electronics realized with discrete techniques (op amp, logic etc).

In att I send schemas. Tests were done with control, without closed-loops. For regulations, we made simulations and got expected results.

What do we need?

1. Realize the final inverter control circuit and inter-communication with DSP. My experience with DSP was in motor drive 3-ph for Zagreb's low flour tramways (179 pcs start at the beginning of 2000 years). We based control on your 2000 platform, but the software was made and applied in Koncar, Zagreb.
2. I’d like to use your C2000TMS320...dsp. According to your app. notes; SPRABW0C, TIDUAY6E, TIDUE53B, specially SPRUAI76 (TMS320F28379D) control card.
3. I kindly ask you to propose me all components I need for too prototypes. I’d like to buy a control unit, without soldering smd etc…
4. Programming support; ? level like Simulink, TiNA, Plecs, but not that we have to write basic software (some C code), but use higher blocks, components from the library. Simulated on PC and download to dsp.? control card in my pcb..? It is not a problem for us to pass your education curse... webinar etc.
5. List of your proposals and estimated price, and your supplier nearest to Croatia.
6. List of useful App. Notes and papers.

In this project, we cooperate with University of Zagreb, Faculty of Electrical Engineering and Computing (FER).

Expecting your answer and help we remain your faithfully
