Abstract
In various arrangements, a nebulizer element of a nebulizer may be energized with a drive signal. A phase offset of the drive signal may be measured. A phase delta may be determined. The phase delta may indicate a difference between a target phase offset and the measured phase offset. The target phase offset may indicate a non-zero target phase difference between the voltage of the drive signal and the current of the drive signal. A frequency of the drive signal may be changed to decrease the phase delta.
