Abstract:
Methods and apparatus to provide a rectifier having a high power factor not limited by voltage ratings of switching devices. Methods and apparatus can include pairs of series-coupled switches coupled to a respective phase signal to, along with respective diode pairs, apportion voltage over a series of load capacitors coupled across the rectifier DC output terminals.
