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 reducing or minimizing one or more of the time-averaged magnitudes of, near DC low frequency AC components 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.
