  • Multi-stage power inverter
    Patent number: 9647574
    Abstract: An inverter for converting an input direct current (DC) waveform from a DC source to an output alternating current (AC) waveform for delivery to an AC grid includes an input converter, an output converter, an input controller, and an output controller. The input controller is configured to control the operation of the input converter, and the output controller is configured to control the operation of the output controller. The input and output controllers are electrically isolated from each other and may be incapable of direct communications between each other. In some embodiments, the input and output controllers may communicate with each other via the input and output converters.

  • Method and system for controlling a multi-stage power inverter
    Patent number: 8611107
    Abstract: A method for controlling an multi-stage inverter comprises controlling an input converter of the multi-stage inverter with an input controller and controlling an output converter of the multi-stage inverter with an output controller separate from the input controller. The input controller and output controller may be galvanically isolated. Additionally, the method may include communicating data between the input controller and the output controller over a power bus of the multi-stage inverter.
