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 1):
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 by,\n calculating an adjusted angle based on a d-axis voltage and a q-axis voltage, the adjusted angle representing a difference 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 due to a voltage drop across an impedance of a filter between the terminal of the AFE inverter and the terminal of the AC grid, the d-axis voltage and the q-axis voltage representing a projection of the AFE inverter terminal voltage vector along a rotating dq-axis, the rotating dq-axis having a d-axis aligned with the synthesized grid voltage vector angle, and \n estimating the synthesized grid voltage vector angle at the terminal of the AC grid based on at least the adjusted angle such that the controller estimates the synthesized grid voltage vector angle to compensate for the voltage drop across the impedance of the filter, the synthesized grid voltage vector angle being an angle associated with a voltage vector of the terminal of the AC grid; \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.
