| When the current flowing in an inductor is quickly interrupted a large voltage spike is observed across the inductor. This large voltage spike can in fact be useful in some cases. One example is the DC to DC boost converter, which is a circuit that can create a larger DC voltage from a smaller one with very high efficiency. The basic idea is to combine an inductive spike generator with a rectifier circuit, as shown in figure 2. Whenever the transistor is abruptly turned off the voltage at the drain spikes up, the diode D< | When the current flowing in an inductor is quickly interrupted a large voltage spike is observed across the inductor.
