The project derives it's motivation from the concept of cost reduction and reuse of components in commercial electronics and cost reduction in lab power supplies.
This particularly targets the use of TAPAS with Raspberry pi or Beaglebone black to design a programmable power supply that can be operated in 1-phase ac/3-phase ac or dc modes with variable voltage output settings. Multiple modes can also be activated simultaneously. The control can be both on the system or over the internet.
The output characteristic variations would be achieved using SPWM as required for the desired output.
A sense circuit is used as a feedback element to correct the generated output to match the desired output.
Once this is achieved, the project goes on to use this feature in designing a "universal socket", which can provide user defined voltage levels in both ac and dc modes.
On the front end, the user connects his device, selects ac/dc and voltage and then selects output ON. Each time a different device is plugged in, a different setting can be applied while the hardware remains same, bringing in re-usability.
This way, Personal Electronic Devices (PEDs) that need individual power cables(with power converters in them) because of difference in their electrical ratings can be powered from this single universal socket. Hence, a single conducting cable with suitable termination can be used for all sorts of PEDs that match the termination of the cable (such as two laptops with barrel connectors for charging but different power ratings), as, the actual power conversion takes place on TAPAS behind the "universal socket".
This way, if standardized and used across industry, a reduction in cost for power adapter cables (such as in laptops) can be achieved as the PEDs now only need a simple conductor cable with proper termination at one end and a TAPAS socket connector at the other end. The user selects the operating voltage and mode while connecting the device to the "universal socket".
This would also result in reuse of the electronics (on the TAPAS system) to power different types of devices.
