I need every trace of that existing branding removed and replaced with a fresh sponsor look (think Tesco or similar) so I can use the piece as a sales-pitch video. The new artwork must appear everywhere the viewer’s eye naturally lands around the track and, beyond that, in a few extra spots inside the circuit. In practical terms that means: • the perimeter boards all the way round • the start and finish lines (checkbox choice) • bends 1, 2, 3 and 4 on the back straight • the starting boxes and the finish gantry I already have some generic sponsor graphics that cover colours, logo and basic layout.

The hardware circuit design and hardware implementation of a 2nd stage voltage adder cell (VAC) integrated with a classical DC–DC boost converter using a SiC MOSFET switch (prototype). The converter is designed to operate with an input voltage of up to 100 V. The proposed non-isolated topology incorporates a dynamic duty-cycle-dependent VAC consisting of an inductor, two capacitors, and a diode. When embedded within a boost-derived structure, the VAC delivers additional energy to the output during the OFF state of the switch, leading to a progressive increase in voltage gain. Some of the important observations in this work include the voltage stress across the passive components, the output performance of the converter—especially its ability to achieve a higher v...
