  • High frequency, high density power conversion system
    Patent number: 6154376
    Abstract: A high-frequency, high-density power conversion system providing lossless power switching with a single or double-ended power converter, the single ended converted including a pair of input terminals for received dc or rectified ac voltage, a transformer with its primary across the input terminals, a transistor in series between an input terminal and the transformer primary, and a dedicated inductor in series between the other input terminal and the other side of the primary, in which the transistor is switched to provide a sinusoidal output current pulse to the transformer primary.
    Type: Grant
