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 16):
The controller of  claim 15 , wherein, when the AFE inverter is enabled, the processor is configured to estimate the second AFE inverter terminal voltage vector angle by running the PLL to:\n calculate a position error between the second AFE inverter terminal voltage vector angle and the d-axis associated with the PLL; calculate an angular frequency of the second AFE inverter terminal voltage vector angle by using a PI controller to regulate the position error; and estimate the second AFE inverter terminal voltage vector angle by integrating the angular frequency.
