Patent ID: 8537583

Claim:
A load driver that applies pulse voltages to a first capacitive load and a second capacitive load, the first capacitive load including a first electrode and a second electrode and the second capacitive load including a third electrode and a fourth electrode, the load driver comprising: a capacitor; at least one coil; and a driver that connects the second capacitive load, the capacitor, and the coil to release charge from the third electrode to the capacitor, connects, after completion of releasing the charge to the capacitor, the first capacitive load, the second capacitive load, and the coil to release charge from the first electrode to the fourth electrode, connects, after completion of releasing the charge to the fourth electrode, the first capacitive load, the capacitor, and the coil to release charge from the capacitor to the second electrode, whereby the pulse voltages of opposite phases is applied to the first capacitive load and the second capacitive load from each other.
