Abstract
An electronic controller is configured to provide control signals to the control terminals of the semiconductor switches of the primary converter and the secondary converter based on a commanded current or target output current; the electronic controller is configured to adjust the phase angle(s), between a respective pairs of semiconductor switches of the primary converter and second converter based on a deadtime compensation module responsive to a current error or current difference between the target output current and the observed output current. A low-pass filter facilitates estimation of the current error for compensation in the commanded current.
