Abstract [sv]

Denna rapport utreder möjligheten till en mönsterkortslösning för en kabelbaserad kraftenhet. Denna kraftenhet är en låda som består av flera komponenter som exempelvis kraftenheter för 24V, 100V, filter och motorstyrkort för två axlar samt kraftfördelning. Kablarna i enheten är tidskrävande och dessutom kostsamma. Därför har enheten idag både hög produktionskostnad och produktionstid. Kablarna tillför, utöver höga kostnader, risk för störningar och p.g.a. mängden kablar ökar svårigheten att felsöka enheten.

Simuleringar har genomförts med LT-Spice för olika RC-filter för styrsignalerna i kraftenheten. Vidare har ett kretsschema konstruerats baserat på ritningen av lådan och alla kablar som ska reduceras och hanteras av mönsterkortet. Med kretsschemat skapades en layout för mönsterkortet. Denna layout representerar alla komponenter och hur kopparledningarna ska placeras. Det ledde till att mönsterkortet utvecklades som en möjlig lösning till kraftenheten.

Abstract [en]

This report investigates the possibility for a PCB (Printed circuit board) solution for a cable-based power unit. This power unit is a box which contains multiple components as for example power units for 24v, 100v, filter and motor control boards fort wo shafts and power supply. The cables in the unit are complicated and hard to construct and also expensive. Therefore, the unit has a high production cost and high production time. Besides high costs the cables also add risks for interference and because of the amount of cables it also raises the difficulty to debug the unit.

Simulations have been done with LT-Spice for constructions of different RC-filters for the steering signals in the power unit. Furthermore, a circuit diagram has been drawn based on the drawing of the power unit and all the cables that are to be reduced and handled by the circuit board. The circuit board layout was designed based on the circuit diagram. Which led to a circuit board being developed as a possible solution for the power unit.
