Gate Driver ICs Forum Discussions

Hello,

I am using an EiceDRIVER 1ED34x1Mc12M for controlling an IGBT but the driver's Ready Signal is always 0.

After applying voltage to the driver FAULT_N switches to 1 (which means no error) but RDYC is alway 0 (which means driver is not ready).

Here is the schematic of my application.

READY and the FAULT Pins of the driver are connected to inputs of my microcontroller. EPWM3a_EN and EPWM3b_EN are connected to the PWM outputs of my controller and configured as outputs.

For testing purpose I only applied 32V to V_HIGH+. As IGBTs I am currently using the RGT50TM65D  from ROHM which is a normal IGBT without Kelvin Source.

I have tried different resistors for ADJA and ADJB but RYDC never changes to 1.

Is there something wrong with my schematic? Do you have any tips for me how I can debug this?

Best regards,

Johannes

Please tell us one point about Gate Driver.
Is it possible to use a CT type 2ch output Gate Driver for the midpoint part of the H6.5 circuit used in the PCS?
If there are independent GND terminals on the H side and L side, I think there will be no problem with the operation itself, but does Infineon recommend using it in a 2ch product?
Or do you recommend using 1ch products?

■ 2ch product model number
・Model number: 2ED020I06-FI
・Model number: 2ED020I12-F2

Best regards，

Hi, I am trying to establish the rise  time of the 1ED3142 gate driver @ Vvcc-Vvee = 20V.

The data sheet states 20nS maximal rise time but no minimum or typical Value.  I would like to achieve as short a rise time as the mosfet  will allow , if possible.

Input capacitance of the Mosfet is 579pF, gate charge is 37nC,  rise time is 8nS.

The function generator has a 7ns rise time output signal.

What will be the probably output rise time of the 1ED3142 gate driver?

Thank you

Hello Community

If the source of a N-channel mosfet is connected to a negative high voltage, and the drain is connected to ground, is there any method to drive the mosfet, without using a isolation transformer ?

this is the problem I encountered  when I try to design a fast pulse generator to produce an edge rising from -4.5kV to 0.

please share your solution.

thanks 

Hi,

Here with, i want to know the Junction temperature (TJ in °C), Junction-to-ambient thermal resistance (ᶿJA in °C/W) & Junction-to-case thermal resistance ᶿJC (°C/W) values ofPVG612S-TPBF IC.

Kindly share the information mentioned above.

Thanks

Hello Community

Please assist me with the formular for calculating the Number of Turns in the Primary and Secondary windings of the Low Frequency DC to AC Inverter Transformer design.

I need to design a 3KVA  low Frequency transformer. Input DC voltage is 24VDC, Output AC voltage is 230 and AC voltage power is 3KVA.

Please let me hear from you

Thanks

What are the UL certifications and or e-file number for International Rectifier part number PVI5033R, Photovoltaic Isolator
Solid-State Opto-Isolated MOSFET Gate Driver?

Hi,

Recently, i am using 2ED28073J06F for motor drive (three phase inverter).

Help to provide recommended layout and routing for COM pins.

Whether the COM pin is arranged on the signal side, and then makes a single point connection with the power side.

For three phase inverter , need to connect 3 times?

Please provide some AP.

Thanks.

Are there any design files (Gerber etc) available for the 2ED100E12-F2 gate driver board? Also, is it possible to purchase these boards from Infineon?
