摘要： A piezoelectric transformer includes at least a pair of monitor electrodes for monitoring unbalanced vibration of the piezoelectric element. The transformer also has a plurality of input electrodes for a transformer input signal and a pair of output electrodes for a transformer output signal. While driven by the input signal to produce the output signal, the piezoelectric transformer produces a pair of monitor signal components at the monitor electrodes to individually indicate vibration components produced in the piezoelectric transformer collectively as a state of unbalanced operation of the transformer.

摘要： In a piezoelectric transformer driving circuit which comprises a boosting circuit (2) for boosting an input direct current voltage, a piezoelectric transformer (3), a current voltage converting circuit for converting a load alternating current which flows in the load (9), and a rectifier circuit (5), an input voltage detecting and comparing circuit (10) compares the input direct current voltage with a minimum voltage which is determined by a setting value of the load alternating current to produce a first voltage having a high level when the input direct current voltage is lower than the minimum voltage and to produce a second voltage having a low level when the input direct current voltage is higher than the minimum voltage. A reference voltage producing circuit (6a) produces one of first and second reference voltages in response to one of the first and second voltages. A main voltage comparing circuit (7) compares a rectified direct current voltage from the rectifier circuit with one of the first and second reference voltages to produce one of primary and secondary voltages. A frequency scanning oscillator (8) determines, in response to one of the primary and secondary voltages, a scanning direction of a driving frequency of a driving pulse signal which is supplied to the boosting circuit to supply the driving pulse signal to the boosting circuit. The input voltage detecting and comparing circuit may supply the first and second voltages to the current voltage converting circuit instead of the reference voltage producing circuit. In this event, the reference voltage producing circuit produces and supplies a reference voltage to the main voltage comparing circuit.

摘要： A combination of two control methods are used, one of which is a method to control the boosting ratio of the piezoelectric transformer and another is a method to control the driving waveform of the piezoelectric transformer. The threshold values for switching the control methods are set with a hysteresis characteristic in order to avoid instability in the driving frequency at the time of switching and also to avoid driving at a natural frequency. When the source voltage is fixed, the driving frequency is increased by changing the resistance of the detection resistor 16 until the driving frequency reaches the natural frequency causing problems. When the driving frequency reaches the natural frequency, the power supply to the driving circuit is reduced to reduce the amplitude of the driving wave for reducing the driving frequency without changing the output voltage. At this state when the amplitude is small, the minimum output voltage is obtained by increasing the driving frequency to the natural frequency. This method and apparatus provide a wider range of output voltages and reliable output characteristics of the piezoelectric transformer.
摘要翻译：使用两种控制方法的组合，其中之一是控制压电变压器的升压比的方法，另一种是控制压电变压器的驱动波形的方法。用于切换控制方法的阈值被设置为具有滞后特性，以避免在切换时的驱动频率中的不稳定性，并且也避免了以固有频率的驱动。当源电压固定时，通过改变检测电阻16的电阻直到驱动频率达到固有频率而引起问题，从而增加驱动频率。当驱动频率达到固有频率时，降低驱动电路的电源以减小用于降低驱动频率而不改变输出电压的驱动波的幅度。在振幅较小的状态下，通过将驱动频率提高到固有频率来获得最小输出电压。该方法和装置提供了更宽的输出电压范围和压电变压器的可靠的输出特性。
