In this paper, the performance of a self-powered
unipolar gate driver supply circuit for power devices is studied,
with the aim of analyzing the viability of using such circuits in
high voltage applications with discrete components. A simplified
model of the circuit, capturing the essential features, is
proposed, from which practical design guidelines are provided
to optimize the overall circuit performance. These design
guidelines allow a proper component selection that can result in
significant improvements in the circuit performance.
Experimental results of typical parameters characterizing the
turn-on and turn-off transients, including the turn-on and turnoff
energy loss, are provided for a wide range of current values
and different gate resistances. The results are compared to those
obtained using a conventional gate driver power supply.
