High frequency series ac voltage regulator


A bidirectional ac series voltage regulator that regulates an output ac voltage level regardless of the varying ac input voltage utilizing high frequency series inductors that only process a proportion of the total output power. The ac series voltage regulator detects the power inductor current direction data signal and can generate power inductor current direction data signals for its control to determine the ac input voltage polarity at all time; wherein the determination of the ac input voltage polarity is unambiguous during the ac input voltage zero crossover and near zero points; and wherein the determination of the ac input voltage polarity allows normal switching sequence of the ac bidirectional switches during the ac input voltage zero crossover and near zero points to prevent power “shoot-through.”.

Display device and drive method therefor


A polarity of a pol outputted from a polarity inversion control section (9) is always identical between a scanning period and a pause period immediately subsequent to the scanning period, and is reversed every time switching from a pause period to a scanning period is carried out. This makes it possible to both carry out pause driving and prevent image sticking on a display panel..
