Implementing monitoring functions
MOSFET and IGBT : Gate Driver and Semi-conductor Monitoring

The voltages at the supply's secondaries are useful both for powering the driver electronics and for defining the control voltages for the power component's gate. Different structures are used, each with its own advantages and disadvantages. The first difference concerns the number of windings on the secondary side of the supply transformer. It should also be noted that the position of the reference potential COM has an impact on the driver electronics, symbolized by the block named "Logic" on figures 12 a, 12 b and
