DC-DC converters - repost


Design 3 types of switching isolated variable voltage output DC-DC converters.

1. Works include:

- design (including initial analysis of alternative topologies);

- full electrical calculations (including magnetics) documented in Word and Excel, allowing parameters variation in a spreadsheet;

- full control loop and stability analysis at various combinations of input voltage, output voltage and load (at least 3 sampling points of each parameter will need to be analysed, meaning at least 27 scenarios in total for each type of converter);

- building 4 prototypes of each type of converter (magnetics will be manufactured according to specification and supplied by us);

- testing all prototypes (12 in total) and confirming all design parameters including loop control stability;

- shipping 9 out of 12 prototypes to Australia;

- full documentation, including schematic and PCB files in Protel 99SE format.

Please read carefully attached "Power converters specification [url removed, login to view]" file. All bidders are required to provide feedback using attached questionnaire file "Power converters follow-up [url removed, login to view]". Please reply in full, especially in regards to testing procedures and test equipment you are planning to use. Your bid will not be considered unless a full feedback is received. Thank you.
