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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pulse width modulation (PWM) for multi-level power inverters","description":"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.
