Active gate control in half-bridge inverters using programmable gate driver ICs to improve both surge voltage and switching loss

Design of a 5MHz half-bridge gate driver for GaN HEMTs with adaptive output current

“…Firstly, the switching power loss in the resistor increases, which reduces the efficiency of the driver. Secondly, the delay increases, which restricts the maxim switching frequency [15,16]. Therefore, it is useful to design an output drive circuit that does not need an external series resistor and can automatically adapt the drive current according to the C L of the power device.…”

Investigation into the Switching Transient of SiC MOSFET Using Voltage/Current Source Gate Driver

“…In contrast, current source gate drivers (CS-GD) have a high output impedance to damp oscillation, and there is no impact of the voltage drop in the gate drive owing to the direct control of the gate current. Thus, some different types of current source gate driver have been proposed to improve the switching performance of power semiconductors, such as constant current gate driver [11], resonant current gate driver [12], hybrid gate driver [13] and programmable current driver [14][15][16]. Despite using different structures, the fundamental features of such gate drivers are similar because of the same inherent current-source characteristics.…”

Analysis of dependence of dV CE/dt on turn-off characteristics with a 1200 V double-gate insulated gate bipolar transistor

“…Gate-control techniques have therefore attracted attention as a means of reducing energy loss throughout the system, including IGBTs and fast-recovery diodes [10][11][12][13][14][15][16][17][18][19] or gate-drive circuits. [20][21][22][23][24][25] Double-gate (DG) IGBT technology is one such gate-control technique. [26][27][28][29] Energy loss can be reduced by using a device with two gates controlled at different timings.…”
