Yes, I can use the TVS diode to protect the gate driver from the inductive kick back voltage instead of going to a new gate driver. I do see the relationship between speed, current, load and inductive kick back voltage.
When the motor is loaded from 80 to 100 % of allowed load at max speed...
The reason for my theory to match the measurement is that I am choosing a gate driver which should be able to handle the inductive kickback voltage. The present gate driver on the board is getting damaged by the inductive kick back voltage.
At 2000 RPM at 90% of load allowed, will generate a 26...
I am trying to calculate the inductive kickback voltage for the motor. I am having a problem matching theoretical calculations with the measured inductive kickback voltage. Can anybody please help me with identifying the issues with my calculations?
Continuous current = 25 A,
Max voltage =...
Hello BradtheRad,
Thank you for the reply, sorry I only drew one diode, but I plan on using two diodes, which will make it 1.4 V. I am using the Schmitt trigger comparator for the interface design. It's better to use comparators than opamps for converting the analog signal into a digital...
I am designing a Variable reluctance sensor interface, I am taking a help from the attached circuit to design the Interface.
I have calculated the threshold values for the VR sensor interface based on the conditions I have mentioned in the attached document.
Va and Vb are the filtered signals...
What is the Maximum current a relay can handle?
Do you thing it can handle 250A? if not why?
I am trying to understand the relay's concept, like how it can be used to Detect and isolate faults on transmission and distribution lines by opening and closing circuit breakers.
sensor will need a conditioning circuit even though it produces a digital output, how about when you touch a sensor with the static field of 8kv that will destroy the input of ECM hence you have a ESD cap and also to remove some of the unwanted frequencies or glitches from the sensor input.
Efficient way to design the VR sensor Interface for ECM for heavy duty, Mid range and Industrial applications.
While going through different interface circuits,
I came up with one design which is as follows.
Input Impedance made of R ||C and this in series with the same values of R||C --->...
Hello Brad,
I was busy last week that's why couldn't reply you. In past posts I was trying to define the criteria for Hall effect sensor interface, Initially I wasn't sure how this is going to work and described what I am doing. Now I know that there was no need of getting a sine wave at the...
Hello Godfreyl
The LPF or signal conditioning circuit is used just to clean up the square wave signal and remove any voltage offsets or slow transients. The ideal output from the LPF or signal conditioning is a clean square wave.
Hello FvM,
Yes, Because the output of the hall effect sensor is square wave and you don't want to pass the square wave to the input of ADC of the microprocessor. This is because ADC won't be able to read it and it will be able to read the sine wave coming from the Low Pass Filter or Signal...
Hello,
I am trying to find the criteria for the Low pass filter selection for Hall effect sensor.
From my understanding If I know the frequency of Hall effect sensor then I can find the R and c values and Design a Low pass filters.
But there are two obstacle mentioned below.
There are two...
Hello,
Any body knows what Electronic Systems Integration Engineer does?
I have an interview for this position and I don't know how to prepare for this.
any help will be appreciated.
Thank you.
