A resonant converter, including a transformer for separating a high-voltage (primary) side from a relatively low-voltage (secondary) side, has at least one synchronous rectifier and an auxiliary sense winding coupled to the gate thereof. The input capacitances of the synchronous rectifiers are reflected to the primary side and the secondary side by the square of the ratio of the number of auxiliary sense winding turns to the number of primary and
