Abstract
A camera flash circuit employing a piezoelectric transformer in the flash trigger circuit, the piezoelectric transformer having input terminals coupled to the main flash voltage storage capacitor and an output terminal coupled to the flash trigger terminal on the flash tube. When the camera flash trigger switch is closed, the input terminals of the piezoelectric transformer are driven directly from the charge voltage stored on the flash storage capacitor to generate the necessary high voltage pulse at the flash tube trigger terminal to initiate firing of the flash tube.
