- Abstract
A new design is presented to decrease the contact wear between a piezoelectric transformer and its heat transfer structure by inserting a layer of polypropylene membrane between them. Without significant degradation of performance, the wear problem is well suppressed with notable extension of working life. Compared with the former wear rate of 2.72% per day on the electrodes in the first 2.5 working days, the wear rate with polypropylene membrane is decreased to only 0.03% per day within an accumulated working time of 110 days. Moreover, with the insulating layer, structure design and package become more flexible as the metal electrodes and radiator are isolated.
