摘要:
The present invention relates to a driver device (40) for driving a load (52) having a plurality of separate capacitive load elements (52), in particular an ultrasound transducer having a plurality of transducer elements (52), comprising: input terminals (44, 46) for connecting the driver device (40) to power supply (48) a plurality of output terminals (50) each for connecting the driver device (40) to one of load elements (52), a first controllable switch (54) connected to a first of the input terminals (44), and a plurality of driving elements (42) each having a second controllable switch (60) and a resistor (58) connected in series to each other, wherein each of the driving elements (42) is connected in series with the first controllable switch (54) and to a second of the input terminals (46), and wherein each of the output terminals (50) is connected to one of the driving elements (42) for powering the load elements (52).
