Chapter 20

Creating High Voltage

Chapter Outline

In previous chapters we’ve discussed voltages of, for example, 15 V and higher. Yet, the radio-controlled cars that we will modify typically use 6 V or 7.5 V battery packs. Where did the extra volts come from?

Recall that inductors and capacitors have the unique properties of maintaining current (in the case of inductors) or voltage (in the case of capacitors). That is, an inductor, operating at some given current, will resist changing that current and a capacitor, operating at some given voltage, will resist changing that ...
