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.
