  • Patent number: 9998033
    Abstract: A stacked voltage source inverter having separate DC sources is described herein. This inverter is applicable to low or medium voltage, low to medium power applications such as photovoltaic utility interface systems, battery storage application such as peak shaving with renewables, motor drive applications and for electric vehicle drive systems. The stacked inverter consists of at least one phase wherein each phase has a plurality of low voltage full bridge inverters equipped with an independent DC source. This inverter develops a near sinusoidal approximation voltage waveform with fast switching and small low pass AC output filter. A system controller controls operating parameters for each inverter. The inverter may have either single-phase or multi-phase embodiments connected in either wye or delta configurations.

  • Patent number: 8884180
    Abstract: A system and method for managing power delivered to a processing chamber is described. In one embodiment current is drawn away from the plasma processing chamber while initiating an application of power to the plasma processing chamber during an initial period of time, the amount of current being drawn away decreasing during the initial period of time so as to increase the amount of power applied to the plasma processing chamber during the initial period of time.

  • Patent number: 8815329
    Abstract: An apparatus and method for controlling an application of power to power a plasma chamber. A detector detects actual power out from the power stage to the plasma chamber during a sampling interval. A compare module compares the actual power out during the sampling interval to a present power setting during the sampling interval and generates a compensation value. An adjust module updates the present power setting for the power stage with the compensation value to provide a new power setting for the power stage to control the power out from power stage to the plasma chamber during the deposition process whereby power losses occurring during the deposition process are compensated during the deposition process. If there is a fixed time period for the deposition process, the compensation method and apparatus may be used to compensate the deposition process for energy losses without extending the duration of the deposition process.

  • Publication number: 20140101462
    Abstract: A power distribution system for data center systems (and corresponding method) feeds DC power directly to a first AC-DC power supply of a computer system in the data center system and feeds AC power to a second AC-DC power supply of the computer system to efficiently and reliably provide an uninterruptible supply of power to the computer system. The power distribution system includes an energy storage unit for supplying the DC power, a charger for charging the energy storage unit, and an inverter through which the energy storage unit provides energy to an electrical substation of an electrical grid. The charger is configured to receive energy from a renewable energy source and the electrical substation. The inverter may also be configured to receive renewable energy from the renewable energy source and supply that energy to the electrical substation. An uninterruptible power supply may be coupled between the electrical substation and the AC power feed.
