Only primary input electrodes (1,2) connected to the two inner electrode groups, a secondary output electrode (40), and the lead electrode of the secondary output electrode in the form of a mesh are exposed on the same surface of the device.

摘要： When an input voltage rises, (the amplitude of) a sine-wave voltage for driving a piezoelectric transformer (1) increases, so that a detection voltage (Vti) rectified by a rectifying circuit (9) also increases. An output voltage from an error amplifier (10) for comparing the detection voltage (Vti) with a reference voltage (Vref2) rises. If the output voltage from the error amplifier (10) rises, a voltage-controlled oscillation circuit (11) decreases the duty ratio of an oscillation signal to be output. In a driving circuit (7), as the duty ratio of the oscillation signal decreases, the amplitude of a fundamental wave contained in a rectangular wave to be output decreases to be a small driving voltage to the piezoelectric transformer (1).

摘要： In a piezoelectric transformer control circuit, when a load (2) is disconnected from a piezoelectric transformer (1) and changes to an open state, an output detection voltage (Vdet) becomes higher than a reference voltage (Vref2), and the output from a voltage comparator (10a) goes “Low”. When the output of the piezoelectric transformer (1) is short-circuited to GND, the output detection voltage (Vdet) abruptly drops to almost “0” and becomes lower than a reference voltage (Vref3). The output from a voltage comparator (10b) goes “Low”. A voltage-controlled oscillation circuit (6) detects the signal “Low” to stop the generation of the oscillation signal to a driving circuit (7) for driving the piezoelectric transformer (1).

摘要： In an electronic flash device, a driving circuit (12) drives a piezoelectric transformer (13) in response to an oscillation signal of a predetermined frequency, which is output from an oscillation circuit (11). A switch (14) is provided in series in a line that connects the output of the piezoelectric transformer (13) and a capacitor (3). When the switch (14) is ON, the output voltage from the piezoelectric transformer (13) is rectified by a rectifier circuit, and charges the discharge capacitor (3) as electric energy for discharging a discharge tube (4). When the switch (14) is turned off, and the output voltage from the piezoelectric transformer (13) is applied to the discharge tube (4), the discharge tube (4) emits flash light by the electric energy stored in the discharge capacitor (3) in response to that applied voltage as a trigger.
