“…Yet, a simple increase in the gate resistance will greatly enlarge the loss. Thus, the authors have proposed a gate drive method by which only the reverse recovery time of the diode and the fall time of the IGBT are prolonged [11,12]. Figure 18 shows the di / dt control gate drive circuit proposed by the authors.…”

“…In addition, as a method of reducing the radiated EMI noise, a di / dt control gate drive circuit is hereby proposed [11,12]. This circuit is a means of reducing only dv / dt at reverse recovery of a diode and the turn-off surge voltage of IGBT.…”

“…Most of this prior work has been targeted at improved voltage sharing among series-connected switches without providing external control of the or rates. An exception is [8], which uses a closed-loop op-amp circuit to actively control the collector voltage during switching transients. Flexible and control techniques are presented in this paper that have been developed to achieve the following two specific objectives: 1) independent control of the output terminal and rates that are adjusted electronically over a wide range without the need to change passive components and 2) maximum compatibility with integrated circuit design techniques that will encourage their eventual implementation in power module configurations that include both the power switches and their integrated gate drives.…”

Abstract-Active gate control techniques are introduced in this paper for flexibly and independently controlling the and of insulated gate power devices during hard-switching events. In the case of control, the output voltage can be controlled over a wide range by electronically adjusting the effective gate-to-drain (-collector) capacitance (i.e., Miller capacitance). For control, similar techniques are applied for electronically adjusting the output current over a wide range using voltage feedback from a small inductor connected in series with the switch's source (emitter) terminal. Both techniques are designed to maximize their compatibility with power module implementations that combine the power switch and its gate drive, including integrated circuit gate drives. Simulation and experimental results are included to verify the desirable performance characteristics of the presented and control techniques.
