For basic and reinforced isolation applications, the package of the gate-driver IC has sufficient creepage and clearance distance to be mounted across the isolation barrier. Figure 7 shows the schematic based on a dual-channel isolated gate-driver IC (e.g. EiceDRIVER™ 2EDS8265...
Figure 6: Schematic diagram of the IGBT turn-off process controlled by a driver chip with Miller clamp function 2.3 Short circuit detection of power devices IGBT and SiC devices vary in their short circuit capabilities. Before using a power device to design a drive system, you must first und...
The driver bias voltages for the three high-side (HS) IGBTs are each referenced to their respective motor phase, which means that the three high-side drivers (connected to the three motor phases) each have their own isolated bias power domains (HS-U, HS-V, and HS-W). In addition, th...

Figure 5. Schematic for the converter pictured in Figure 2. This converter takes an 18V-to-90V input and produces a 2.5A output at 12V. IGBT Controller Supply for Automotive Applications The LT3748 can easily produce multiple isolated supplies to power IGBTs that drive synchronous motors from...
IGBT switch off phase • V is the voltage applied to the gate of the IGBT • Ipeak_off is the peak current during turn off • roff_min is the minimum internal off resistance of the gate driver (11) (12) 4.2.2.2 Gate Resistor Dimensioning Equation 13 calculates the approximate power...
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 ...
