DRIVE CIRCUIT FOR PIEZOELECTRIC STACK |
摘要 |
<p>A drive circuit for a piezoelectric stack which drives a desired mechanical object such as a printing head of a dot matrix printer or an ink jet printer. A winding is connected in series with one of electrodes of the piezoelectric stack so that an excitation voltage is applied to the stack via the winding. An excessive charge current at each time of drive and an excessive discharge current at each time of recovery are prevented.</p> |
