Abstract
A system includes a controller for a direct-current (DC) to alternating current (AC) inverter, the controller comprising: a memory configured to store instructions; and at least one processor configured to execute the stored instructions to perform operations including: generating a fault condition Pulse-Width Modulated (PWM) signal to control an active discharge of the inverter in a fault condition by alternately: turning on a first switch group of the inverter while turning off a second switch group of the inverter, and turning on the second switch group of the inverter while turning off the first switch group of the inverter.
