FPGA Implementation of an Optimal IGBT Gate Driver Based on Posicast Control

In this paper, we propose an insulated gate bipolar transistor (IGBT) gate driver that provides an optimal gate signal to manage the IGBT switching mechanism, without the need of a feedback current measurement across the parasitic inductance of the circuit. Our approach is based on the Posicast method, which allows determining an optimal gate signal shape from pulses whose characteristics are determined from the IGBT model. Experimental results demonstrate the effectiveness of the proposed method to minimize electrical switching constraints.
