The hardware circuit design and hardware implementation of a voltage adder cell (VAC) integrated with a classical DC–DC boost converter using a SiC MOSFET switch. 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 voltage gain and the thermal behavior...

My Mimaki printer (main PCB V36-1) has triggered error 155 and I need a knowledgeable technician to walk me through the fix in real time. I’m specifically after step-by-step guidance rather than handing the machine over, and I’m happy to hop on a live video call for visual checks or continuity tests as we progress. I’ve resolved similar faults in the past, so you won’t need to start from absolute basics—just lead me through the precise diagnostic sequence and component-level repair. On my bench I already have the usual hand tools plus a multimeter; if more specialised readings are required, let me know so I can arrange them in advance. The goal is straightforward: clear error 155 and confirm stable boot without recurring alarms. Once you provide the procedur...
