A resonant galvanically separated power MOSFET/IGBT gate driver

Summary, in English

This paper provides a complete circuit for a low-loss non-conventional power MOSFET or IGBT driver. The driver, which provides galvanically separated input and output signals, is fed from a unipolar DC voltage but provides a bipolar gate-source voltage. The driver applies two, already known, techniques and together they form a resonant galvanically separated power MOSFET/IGBT gate driver. The first technique provides the galvanic separation, voltage level increase (or decrease) for the energy supply and signal transfer to the second technique. The second technique is the driver circuit, which is a resonant circuit that provides good driver properties. Together they form an inexpensive and non-complicated circuit, compared to conventional MOSFET or IGBT drivers. The use of expensive DC-DC converters is avoided and still bipolar gate voltages are provided
