Abstract
An electronic controller is configured to adjust the duty cycle, between a respective pairs of semiconductor switches of the primary converter of a direct-current-to-direct-current converter based on reducing or minimizing one or more of the first estimated line-to-line DC offset voltage, the second estimated line-to-line DC offset voltage, and the third estimated line-to-line DC offset voltage. Further, the electronic controller is configured determines duty cycle adjustments based on oversampling (e.g., enhanced data processing with interpolation) of smoothed or integrated representation of the first estimated line-to-line DC offset voltage, the second estimated line-to-line DC offset voltage, and the third estimated line-to-line DC offset voltage.
