A User-Friendly Reconfigurable Testbed System and Method to Test and Validate the Power Electronics Circuits for Educational and Research Purposes

This study discusses a reconfigurable testbed system that is easy to use and tests circuit and power electronic converter systems in power engineering research. Features of the reconfigurable power electronics testbed system include hardware protection against failures such as sudden overvoltages, undervoltages, and overcurrents. The testbed has six voltage and current sensors available to sense the circuit's voltage and current. The voltages and currents detected by the sensors are displayed on the sensor's voltmeters and ammeters that are attached to the sensors. The testbed has input and output voltmeters to show the measured input and output voltages of the completed circuit. The user has the flexibility to create a variety of power electronics circuits thanks to the availability of IGBT switches and passive circuit components like capacitors and inductors. By creating an external electrical connection, all topologies that call for a minimum of 1 switch, a maximum of 12 power electronics switches, constant or variable inductors, and capacitors in the specified voltage and current range may be made possible. Users can utilize the testbed's internal controller or add their own external controller to create a variety of circuits. In this paper, an example with synchronous boost and synchronous cuk converter is shown.
