WebMar 29, 2024 · \$\begingroup\$ The fact that the body diode is activated at low input voltage is a classic and should not bring higher losses in the transistor: the transformer is fully demagnetized and what you see is the energy stored in the capacitance lumped at the drain going back and forth between the primary inductance and this capacitance. What you … WebJun 11, 2024 · The Kelvin connection is basically a dedicated small signal connection straight from the SOURCE/EMITTER of the die dedicated for control. The reason this is done as oppose to using the SOURCE/EMITTER which carries the main current is to mitigate inductive voltage changes on the gate-source/emitter when switching current.
