摘要: Off line converters should be designed to drain almost sinusoidal current from the utility accomplish international regulations about harmonic injection. A common approach is use power factor pre-regulators, that usually, cascaded by a DC/DC converter obtain fast regulated output voltage in load or DC bus. There are also several single stage solutions make these two tasks using one converter, obtaining advantages point of view efficiency, size cost. In this paper, new family AC/DC circuits proposed. With converters, high and tight achieved. This has such as efficiency over structure, simplicity other solutions.
