It is all in battling Mother Nature. She likes continuity and easy flow, e.g. Sine waves, exponentials and Gaussians. But, we give her V(t) = L*di/dt and I (t) = C*dv/dt Every wire represents an inductance, and every junction a capacitance. For high voltage, we should be concerned about the trace-to-baseplate capacitance. EE467/567 Integrated Power © 2010, D. C.

For step-up (the most common application), capacitors are charged in parallel and discharged in series. Often the source is added to the series configuration to increase the
