Hello. I'm a relatively new student studying EEE in polytechnic. The homework is to design and build a toy solar car. Our group decided to add in a booster circuit to help the car move faster, however we have very little idea as to how to make a booster circuit. What does it comprise of? Capacitators and op amps? Our lecturer said that puting just an op amp to the DC supply would burn it out due to the high current, so I'm guessing a relay? Could someone please help us? A circuit diagram would be a great help.
