+The hardware platform of the voltage/current (U/I) Source
+basically consists of a low-cost microcontroller and a Sepic
+converter circuit. Figure 6 shows the hardware block diagram
+of the U/I Source circuit.
+The PC application communicates via USB with a low-cost,
+Cortex-M3 microcontroller LPC1343 [11] from NXP [12].
+This microcontroller features, besides standard μC peripherals,
+a built-in USB bootloader mode, which enables students, in
+case of a firmware update, to upgrade the μC firmware by
+themselves.
+The Sepic converter circuit is built upon discrete components,
+which helps students to understand, how converter
+circuits are operating. Hence, the inductor current, the diode
+current, the output current, and the output voltage is measured
+
+by current monitors. The sample data of these currents is
+transmitted to the PC application and displayed within a graph.
+This additional feature enables students to investigate the
+operating modes of the Sepic converter circuit. As part of
+the research process, courses at the university were precisely
+analyzed. The result of this analysis is represented in Table IV.
+
+The U/I Source is USB powered and features standard
+laboratory output connectors to supply an external load. Furthermore,
+this device is as small as a standard credit card,
+which makes it easy to transport. The PC application, which
+is used to configure the hardware platform and to display the
+measured currents & voltages, is described in section IX-D.
