Abstract
An isolated DC/DC converter includes: a transformer having a primary side and a secondary side; an inverter configured to change a DC input voltage (Vin) to an AC current for energizing the primary side of the transformer; a capacitor in series with the primary side of the transformer; and a controller configured to operate the inverter in a first mode such that the capacitor pre-charges to |Vin| before the controller receives a turn ON command, the capacitor charges to X*|Vin| during a first part of a first switching cycle after the controller receives the turn ON command where X>1, and the capacitor voltage resonates with a magnetizing inductance of the primary side of the transformer during a second part of the first switching cycle. A power electronics device that includes the isolated DC/DC converter is also described.
