Abstract
A DC--DC boost converter for directly driving a capacitive load employs four switches for cyclically commuting the connection configuration of an energy storing inductor. First and second switches are driven at a relatively high frequency and provide an impulsive charge path of the inductor by connecting one or the other end to a power supply rail. Third and fourth switches are driven in phase opposition to each other at a relatively low frequency and provide a discharge path from one and the other end of the inductor, respectively, toward an output node of the circuit to which the capacitive load is connected.
