  • Bootstrap charging by PWM control
    Patent number: 10784797
    Abstract: A power conversion system includes a controller that generates switching control signals according to duty cycles for a current switching control cycle, and adjusts the duty cycles by a non-zero offset value according to a modulation index in response to the modulation index exceeding a non-zero threshold. A method includes computing first duty cycles according to a modulation index, generating a plurality of switching control signals according to the first duty cycles in response to the modulation index being less than or equal to a non-zero threshold, computing second duty cycles offset from the first duty cycles and generating the plurality of switching control signals according to the second duty cycles in response to the modulation index exceeding the non-zero threshold.
