Abstract
The power conversion module includes a power converter coupled to provide a DC output voltage from an input voltage source. The power converter may have primary and secondary stages, and the power converter may also provide a DC output voltage that is electrically isolated from the input voltage source. Additionally, the power conversion module also includes a voltage controller configured to measure a pre-bias value of the output voltage prior to start-up of the power converter and provide a start-up control signal, wherein the start-up control signal corresponds to an initial output voltage that is greater than the pre-bias value of the output voltage. The initial output voltage includes a start-up voltage margin above the pre-bias value and is maintained for a margin hold time. A method of operating a power conversion module is also provided.
