Abstract:
A drive circuit for driving a plurality of capacitive loads, the drive circuit comprising:a first switching transistor, connected between a first source line and an output line wherein the output line is connected to one of the capacitive loads, for supplying electric power from the first source line to the one of the capacitive loads through the output line,a first thyristor having an anode connected to the output line,a first power recovery line connected to the cathode of the first thyristor, anda power recovering block connected to the first power recovery line for recovering the electric power supplied through the first power recovery line,wherein the power recovery block has a storage capacitor connected between a node connecting the first power recovery line with a second power recovery line and a second source line, for temporarily storing the electric power recovered from the output line.
