Piezoelectric transformer driver unit e.g. for fluorescent lamps, has pulse width modulation control providing signals of equal phase and frequency for synchronous operation of drivers, transformers, piezoelectric elements and loads

摘要

The transformer driver unit has a pulse width modulation control (1), providing output signals of equal phase and frequency fed to a number of drivers (2), for driving corresponding transformers (3), coupled to piezoelectric elements (4) for respective loads (5).
