  • Patent number: 9837925
    Abstract: The present disclosure provides a capacitor-less AC/DC converter power supply system. The power supply system includes one or more rectifier cells having inductive and synchronous elements, and removing any capacitive filter elements thus ensuring a very high Mean Time Before Failure (MTBF) on the rectifier stage. The output voltage and current generated by the one or more inductive cells is a DC signal having a ripple amount dependent upon the number of cells implemented.

  • Patent number: 8942019
    Abstract: A multilevel inverter circuit includes an inverter control circuit that controls switching of main and neutral switches. The inverter control circuit receives current vector information indicating flow direction of an AC current output of the multilevel inverter circuit. The inverter control circuit eliminates dead time between switching of a neutral switch and a main switch depending on whether the AC current output is flowing towards a load or away from the load. Among other advantages, elimination of dead time improves the total harmonic distortion of the sinusoidal AC voltage output of the multilevel inverter circuit.

  • Publication number: 20140313803
    Abstract: A method for generating an AC power signal using a transformerless DC/AC converter includes energizing a first inductor circuitry from a DC input source by controlling first, second and third switches to couple the first inductor circuitry to the DC input source; de-energizing the first inductor circuitry by controlling the first, second and third switches to decouple the first inductor circuitry from the DC input source and couple the first inductor circuitry to an output node to generate, at least in part, a first half cycle of an AC power signal at the output node; energizing a second inductor circuitry from a DC input source by controlling fourth, fifth and sixth switches to couple the second inductor circuitry to the DC input source; and de-energizing the second inductor circuitry by controlling the fourth, fifth and sixth switches to decouple the second inductor circuitry from the DC input source and couple the second inductor circuitry to the output node to generate, at least in part, a second half cyc
