  • Patent number: 9716444
    Abstract: Provided is a method for controlling operation of semiconductor gates in a power conversion system including one or more multilevel inverters coupleable to a modulator and a controller. The method includes generating, via the controller, a control signal responsive to an output current power factor associated with the inverters and producing a discontinuous pulse width modulation reference signal based upon the control signal and a target output power, the discontinuous pulse width modulation reference signal being indicative of shifting a phase angle between current and voltage. A gating signal is generated for output from the modulator, as a function of the reference signal and a carrier waveform. The gating signal adjusts the phase angle to prevent switching of the semiconductor gates.

  • Patent number: 9654028
    Abstract: A system and method for operating an inverter to maximize an overall efficiency of a power system is disclosed. A power system includes an inverter having an arrangement of switching devices that are selectively operable in On and Off states to invert a DC output to an AC output having controlled current and voltage. A controller selectively controls operation of the arrangement of switching devices via a discontinuous pulse width modulation (DPWM) scheme, so as to regulate an average voltage of the AC output. In controlling operation of the arrangement of switching devices via the DPWM scheme, the controller is programmed to generate a DPWM reference waveform having an initial phase angle, determine a system efficiency of the power system during operation, calculate an optimal phase angle for the DPWM reference waveform based on the determined system efficiency, and generate a DPWM reference waveform having the calculated optimal phase angle.
