Need for a Gate Driver The structure of an IGBT/power MOSFET is such that the gate forms a nonlinear capacitor. Charging the gate capacitor turns the power device on and allows current flow between its drain and source terminals, while discharging it turns the device off and a large volta...

NOVOSENSE's high voltage isolated driver NSI6611 is used to drive the IGBT and SiC modules; the current sampling circuit and resolver-to-digital converter are used to control motor operation. Figure 1: Block diagram of the main drive electronic control system In the main drive electronic control...
1ED3321MC12N belongs to the EiceDRIVER™ Enhanced 1ED332x family (F3 family). 1ED3321 offers short-circuit protection (DESAT) for IGBTs and SiC MOSFETs. The driver IC implements separate source / sink outputs, operates over a wide supply voltage range, either unipolar or bipolar and has ...
This metric is generally taken as the be-all and end-all for the drive strength of the gate driver. The time to turn a MOSFET/IGBT on and off relates to the current that the gate driver can deliver, but it doesn’t tell the whole story. The term peak current is so widespread in ...
EiceDRIVER™ Compact single-channel isolated gate driver with 6 A sinking and sourcing peak output current and 13.6 V UVLO in DSO-8 narrow-body package for IGBTs, MOSFETs and SiC MOSFETs.
The STGAP4S is a galvanically isolated single gate driver for IGBTs and SiC MOSFETs with advanced protection, configuration and diagnostic features.

A high power IGBT requires isolated gate drivers to control their operations. Each IGBT is driven by a single gate driver that is isolated from the high-voltage output to the low-voltage control inputs. Also, as the emitter of the top IGBT floats, it necessitates the using of isolated ...
It is important to decide on the power requirement to drive the IGBT. The calculation of gate drive power requirement for different power ratings of variable speed drives is explained in Equation 1. As noted earlier, an isolated gate driver is used to turn the IGBT on and off. In this ...
