Abstract [sv]

Dagens flygfarkoster innehåller avancerad elektronik som ställer högre krav på elförsörjningen när de står parkerad på mark. För att kunna testa elförsörjningen(GPU) behövs AC-laster som är mer varierbara än en enkel resistiv last. I denna rapport undersöks möjligheten att köpa eller konstruera sådana AC-laster.

En marknadsundersökning genomfördes för att undersöka om det finns lösningar på marknaden idag. Det visade sig att det finns flera företag som erbjuder olika lösningar för detta, men att specifikationerna för dem är svåra att tolka och dessa lösningar är också väldigt dyra.

En egen konstruktion togs även fram för att kunna använda en befintlig enkel resistiv last på ett smartare sätt. Genom att kontrollera lasten med halvledarreläer kan snabba återkommande förlopp simuleras. Kontrol-len av reläerna kontrollerades med hjälp av en mikrokontroller, som på ett enkelt sätt kan uppdateras med nya program för att erhålla olika testcykler.

Abstract [en]

Today's aircraft contain advanced electronics that place higher demands on power supply when parked on land. In order to test the power supply (GPU), AC loads are more varied than a single resistive load. This report examines the possibility of purchasing or constructing such AC loads.

A market investigation was conducted to investigate whether there are solutions on the market today. It turned out that there are several companies offering different solutions for this, but the specifications for them are difficult to interpret and these solutions are also very expensive.

An own design was also constructed to use an existing single resistive load in a smarter manner. By controlling the load with semiconductor relays, rapid progress can be simulated. The relays are controlled by a microcontroller, which can easily be updated with new programs to obtain different test cycles.
