Publication number: 20250149996Abstract: A three-level power factor rectifier includes a diode bridge arm, a bridge arm assembly, an input inductor, a capacitor bank, and a controller. The first bridge arm includes a first switch, a second switch, a third switch, and a fourth switch connected in series and in sequence. When the controller determines that a loading is less than a load threshold, the controller controls the three-level power factor rectifier entering a burst mode. In the burst sleep period, when a voltage value of an AC power source is greater than a first threshold, the first switch and the second switch are turned off; when the voltage value is less than a second threshold, the third switch and the fourth switch are turned on. When entering the burst period from the burst sleep period, the controller turns on the second switch and the third switch for a specific time period.Type: ApplicationFiled: March 21, 2024Publication date: May 8, 2025Inventors: Yi-Li SU, Chien-Hung LIU, Wen-Lung HUANG, Chang-Hung LIAO, Po-Yi YEH
