What is the relationship between the magnitude of the IGBT turn-off voltage (e.g. -9V vs. -15V) and the turn-off time, turn-off voltage spike, and losses?

Show LessI hope this message finds you well. I am reaching out regarding a couple of questions I have about the datasheet for the IR2109(4)(S).
Firstly, I am curious about the capacitor specifications mentioned in the datasheet. I noticed that polarized capacitors are recommended for certain applications. However, I am interested in exploring the possibility of using non-polarized capacitors instead. Could you kindly provide some insight into whether non-polarized capacitors can be safely substituted for the polarized ones mentioned in the datasheet?
Secondly, upon attempting to calculate the value of the bootstrap capacitor using the provided formula, I encountered an unexpected result. Specifically, when I substituted the given values into the formula, I found that the denominator resulted in a negative value: (Vcc - Vf - VLs - Vmin) = (12V - 1V - 2.35V - 9V) = -0.35V. This negative value raises some concerns and prompts me to seek guidance on how to proceed with determining the appropriate value for the bootstrap capacitor. Could you please provide clarification on whether a negative value in this context is valid, or if there might be an alternative method or consideration to account for in this calculation?
I understand the importance of adhering to recommended component specifications and calculations, but I am curious about any potential flexibility or alternative approaches in these matters. Any guidance or clarification you could offer on these issues would be greatly appreciated.
Thank you very much for your attention to these inquiries. I look forward to hearing from you soon.
Best regards,

Part Number : IRLML6402TRPBF
I need RoHS, REACH documentation for that part.
I would like to receive a link to receive the materials or a reply by email.
When MOSFET driving resistive load current and voltage changes instantaneously but for inductive load why MOSFET voltage VDS gets clamped ??
Hi everyone,
I want to show the motor voltage to the users, and for that i will use the MotorVoltage register.
I am having a bit of problem with the conversion from codes to V RMS.
The Max_Vdcsense is 500V so, using this formula, when the codes are 4974 the motor voltage is approximately 118 V RMS.
But i am using an triphasic induction motor (230V 50Hz), and in the script Induction motor control by iMOTION™ (infineon.com) the max Vq_Ext = 4974, but the max voltage in each phase should be 230V, right?
I would apreciate some clarification.
Best Regards,
Paulo
Show LessDoes anyone know the reverse recovery time of the IQE006NE2LM5CGSC? The datasheet doesn't show it, is there a#IQE006NE2LM5CGSCny other way to know?
Show LessCould you please teach the failure rate of the VCP function (17pin) of TLE9461ES?
The gate signal of the battery's reverse connection protection FET is driven by this charge pump. If the VCP function is lost, the system may malfunction. Therefore, I would like to know the failure rate of individual parts.
Best Regards,
Tetsuo
I have the following circuit to drive a 3 phase BLDC motor, I'm generating a 20kHz PWM signal for the MOSFETs, however I'm not sure about the correct pulse width I should use to conmutate the MOSFETs, I'm expecting 15A when the motor is starting and approximately 10A when driving.
The MOSFETs I'm using are the IRFB7730 , VGSon would be 12V, VDS ranges from +54.6V (full charge) and +48V, can anyone help please? I just want to know the recommended maximum pulse-width, and minimum pulse-width.
Show LessHello,
The three phase inverter simulation for the CIPOS IPM line is not working again. Ive tried different browsers, networks and computers as well as my phone. Is there a way I can get this working ASAP?
It was working before, i see the landing page at least but it has no simulation tools.
