Microcontrollers werken vaak op 5Vdc. Veel andere logica IC’s (Transistor Transistor Logics) werken ook op 5Vdc. Voor een kleine robot is 5 Vdc dan ook een ideale werkspanning en er zijn ontelbare voorbeelden te vinden op het internet. Er is op het gebied van de µ-controllers wel een trend te bespeuren naar controllers met een lagere werkspanning omdat deze minder warmte genereren. Daardoor kunnen ze bij hogere frequenties werken.
Echter zodra uw robot iets groter wordt dan kan het zonder meer handig zijn om een tweede werkspanning in uw ontwerp op te nemen. Vaak zit het probleem in de aandrijving. Bij een zwaardere robot zal de aandrijving robuuster moeten worden uitgevoerd dan dat met 5Vdc mogelijk is. De volgende standaard waarde voor aandrijving is 12Vdc. Omdat deze waarde ook in auto`s en op boten wordt toegepast, is er veel apparatuur en documentatie te vinden op het internet.
Deze regelbare voedingseenheid kan worden ingesteld tussen 1,8 - 10 Vdc, bij 100Watt (5Vdc=>20A, 140Watt piekbelasting) vanuit een standaard 12Vdc autoaccu. Verder levert deze schakeling een uitstekend stabiele voeding, ook als de 12Vdc voeding pieken of dalen vertoont. Deze schakeling is dus geschikt voor experimenten met diverse spanningen.
De schakeling is opgebouwd rond een Fairchild LM741 operationele versterker. Pin 2 is in In- en pin 3 is de In+. Pin 2 is aangesloten op de eigen uitgang. Pin 3 is aangesloten op de uitgang van de potmeter. De uitgang wordt gevoed aan een BD241B of in ons geval een BD241C. Aansluitend worden 2 2N3055 vermogenstransistoren paralel gevoed om een een flinke uitgangsstroom te kunnen bereiken. Maximum belasting is 100 watt, piek belasting 140 watt.
