Abstract
A controller may include a memory having computer-readable instructions stored therein; and a processor configured to execute the computer-readable instructions to generate Pulse Width Modulation (PWM) signals to control power switches of an Active Front End (AFE) inverter based on at least a synthesized grid voltage vector angle at a terminal of an alternating current (AC) grid without using physical voltage sensors at the terminal of the AC grid, and control the AFE inverter to supply power to a load based on the PWM signals.
