We disclose a new method for the joint detection of phase, frequency and amplitude of AC line voltage

that can outperform existing solutions in terms of detection precision and robustness to noise and

distortions on the AC line. This method is a fundamental building block in digitally controlled AC/AC

power converters, allowing them to operate with a tight adaptation to the input AC voltage, which in

turn brings more efficiency, more precise output control, and less conversion outages due to input AC
