Abstract:
1. A method of bus control comprising: inputting measured power into a bus voltage command calculator of a dc link inverter; inputting measured grid voltage into a bus voltage command calculator of a dc link inverter; identifying the setting of a phase shift selection indicator; at the bus voltage command calculator, using the inputted measured power, the inputted measured grid voltage, and the setting of the phase shift selection indicator to determine a bus voltage command setting output from the bus voltage command calculator; using the bus voltage command setting output for setting the voltage of a capacitive bus positioned between a dc-dc boost converter and a dc-ac converter of a dc link inverter; and when the phase shift selection indicator is in a phase shift authorization setting, using the inputted measured power, the inputted measured grid voltage, and the status of the phase shift selection indicator to determine an output current phase angle command setting.
