Abstract

See full text

A capacitive load drive is provided, which can perform faster and more efficient operation than an energy recovery circuit for effectively reducing ineffective energy of pulses applied to a capacitive load. An energy recovery circuit is connected to a first electrode of the capacitive load, to which pulses are applied. The energy recovery circuit comprises a coil and a capacitor connected in series for energy recovery, and a first and a second voltage clamp switches connected to the other terminal of the series circuit of the coil and the capacitor, the first voltage clamp switch being connected to a high voltage side terminal of the DC power supply, the second voltage clamp switch being connected to a low voltage side terminal of the DC power supply.
