<p>A pre-drive circuit for controlling the turn on/turn off of a MOS FET via a pulse transformer. Between the secondary side of the pulse transformer and the MOS FET, there is provided an element which electrically shuts off the pulse transformer from the MOS FET when a voltage across the gate and the drain of the MOS FET has dropped to some extent toward the negative side, such that the gate - drain voltage of the MOS FET will not excessively plunge into a negative value.</p> |
