An isolating IGBT halfbridge driver module with embedded magnetics

A compact IGBT halfbridge driver module is presented. The driver is based on PCB embedded magnetics. A single inductive coupling element is used for galvanic isolation of the gate control and diagnostic feedback signal as well as for the gate drive power supply. The operation of the driver is described in detail, just as the mechanical construction which aims on volume production. Applications oriented data and test results are given.
