摘要:
A device for driving a load reactance element, such as a piezoelectric actuator for a fuel injection system, including a series reactance element connected in series with the load reactance element, and a resonance circuit formed by the load reactance and the series reactance. First and second switching elements are connected between the resonance circuit and the power source or ground potential. Each of the first and second switching elements is rendered conductive only during a half cycle of resonance. The directions of the load current flowing through the load reactance element are switchable by making alternately the first and second switching elements conductive.
