摘要： A driving circuit is composed of a discontinuous rectangle wave oscillator and a lowpass filter. A discontinuous rectangle wave used herein is composed of voltages Vp, 0 and −Vp. Assuming one cycle is T, a discontinuous rectangle wave has such a configuration that a potential from a time 0 to a time ø is a potential 0, from the time ø to a time (T/6−ø) is a potential Vp, from the time (T/6−ø) to a time (T/3+ø) is a potential 0, . . . . Since the third harmonic wave is not included in the discontinuous waveform, the inductance of the lowpass filter can be reduced. Consequently, the lowpass filter may be omitted. Further, the amplitude of the fundamental wave can be changed by varying the phase difference ø.
摘要翻译：驱动电路由不连续的矩形波振荡器和低通滤波器组成。这里使用的不连续的矩形波由电压Vp，0和-Vp构成。假设一个周期为T，则不连续矩形波具有从时间0到时间ø的电位为0的结构，从时间ø到时间（T / 6-ø）为电位Vp，从时间（T / 6-ø）到一个时间（T / 3 +ø）是一个电位0。。。。由于三次谐波不包括在不连续波形中，所以可以降低低通滤波器的电感。因此，可以省略低通滤波器。此外，可以通过改变相位差ø来改变基波的振幅。

摘要： A dimmer noise reducing circuit wherein vibration noise accompanying the activation/deactivation of a piezoelectric transformer can be reduced, while non-uniformity of brightness of a discharge lamp can be prevented. A chopping circuit turns on/off an output from an input voltage source in a given periodic manner and a full-bridge circuit that receives an output voltage (vb1) of the chopping circuit. An output from a lowpass filter is supplied to a piezoelectric transformer, an output current of which (Io) is supplied to a discharge lamp. The full-bridge circuit is controlled by a full-bridge drive circuit to switch the input voltage (VB1) from the chopping circuit. The drive frequencies of the FETs of the full-bridge circuit are decided by a voltage-controlled oscillator. The chopping circuit is connected to a duty varying circuit the full-bridge circuit is caused to operate with its duty fixed.
