Abstract:
A controller including a memory having computer-readable instructions stored therein; and a processor configured to execute the computer-readable instructions to: estimate a synthesized grid voltage vector angle at a terminal of an alternating current (AC) grid based on at least an adjusted angle, to generate Pulse Width Modulation (PWM) signals to control power switches of the AFE inverter based on at least the synthesized grid voltage vector angle, and to control the AFE inverter to exchange power between the AC grid and a load based on the PWM signals.

Claim (Index 23):
A controller comprising:\n a memory having computer-readable instructions stored therein; and a processor configured to execute the computer-readable instructions to:\n estimate a synthesized grid voltage vector angle at a terminal of an alternating current (AC) grid, the synthesized grid voltage vector angle being an angle associated with a voltage vector of the terminal of the AC grid, and the adjusted angle representing a shift in phase angle between an Active Front End (AFE) inverter terminal voltage vector angle at a terminal of an AFE inverter and the synthesized grid voltage vector angle, the AFE inverter terminal voltage vector angle including a first AFE inverter terminal voltage vector angle and a second AFE inverter terminal voltage vector angle, the first AFE inverter terminal voltage vector angle being an angle associated with the voltage vector of the terminal of the AFE inverter at an initial time and the second AFE inverter terminal voltage vector angle being an angle associated with the voltage vector of the terminal of the AFE inverter at a second time subsequent to the initial time, and the processor is configured to estimate the synthesized grid voltage vector angle by:\n estimating the first AFE inverter terminal voltage vector angle when the AFE inverter is disabled, \n estimating a terminal voltage of the AFE inverter when the AFE inverter is enabled, the terminal voltage of the AFE inverter being a voltage of the terminal of the AFE inverter, \n determining the second AFE inverter terminal voltage vector angle when the AFE inverter is enabled, and \n estimating the synthesized grid voltage vector angle based on the adjusted angle and the second AFE inverter terminal voltage vector angle; \n \n generate Pulse Width Modulation (PWM) signals to control power switches of the AFE inverter based on at least the synthesized grid voltage vector angle; and \n control the AFE inverter to exchange power between the AC grid and a load based on the PWM signals.
