<p>The high speed driving circuit for MOSFET transistors comprises a first coupling transformer (T1), which is driven on the side of the driving logic (IC1) and has a turns ratio of 2:1, with minimum reactance and very high immunity to dV/dt. The circuit comprises a first stage of the driver, constituted by a small MOSFET transistor (Q1), and a second stage of the driver, which is directly coupled to the drain pin of the first stage (Q1). The circuit furthermore comprises a third stage of the driver, which is supplied with two distinct voltages; these power supplies are provided by a second transformer (T2). <IMAGE></p> |
