    H bridge circuit simulation in LTSpice

    I am referring to the video SVPWM and at 6.06 I tried to simulate the same circuit in LTspice, two issues i am facing a. I am not able to create a neutral point by connecting two DC power supplies, is neutral here same as ground? b. The voltage across AB is not VDC or 15V which is expected...

    CAN message Intel and Motorola format

    Ok one thing i understood is that the CAN Byte order and the bit order is fixed which i have not realized earlier, hopefully i will not make mistake in future.

    Simulation of MOSFET

    Thank you i had the older version of LTspice and it did not show the pick new mosfet, now after updating i can see that option.

    CAN message Intel and Motorola format

    I have several times read through the documents to understand the motorola and intel format for creating the CAN dbc file or to interpret the CAN messages, but i always end up in confusion. Please help me with any technique to remember it. One of the documents i always refer in case of confusion...

    Simulation of MOSFET

    First time i am simulating the MOSFET using LTSPICE, please help me to understand the output voltage i am getting, it is around 14.75 V. How is it? i selected the NMOS in the library.

    Clarifications on the schematics

    Yes the same signal on page5 and page6, the circuit i assume measures the Backemf voltage STL180N6F7 The Datasheet i have attached. I have found one link below STLink explaining the logic. I do not understand what he is trying to explain in the stlink.

    Clarifications on the schematics

    I am trying to run motor using the ST board B-G431B-ESC1 and the schematics are available in the link provided(I could not attach schematic as it is big). But i have several doubts, a. There is OUT1 signal on page5, my understanding is it will be between 0 and V+, 0 when Low MOSFET is ON and V+...

    Electric circuit analysis

    I am trying to analyze the below circuit The circuit is basically for reading the DC Bus voltage from the battery voltage, as of now i have given 12V only for testing purpose. My question is when i simulated the voltage across R2 it is 0.75V, what is the impact of having the capacitor C1...

    Difference between Board Supply and Motor Supply

    I am referring to the NXP motor controller evaluation board NXP motor evaluation board and when i refer the quick start guide Quick guide the external power supply is 8 - 18V, but the PM motor connected is 24V. My understanding is 24V or motor voltage is generated from the external power supply...

    Sensor clarification

    I have seen a data sheet, it has got 3 pins supply, ground, output and it is hall type sensor. The output type is Open drain- digital, Output. He is also giving Output high -> 3 - 4V Output low -> 0.5 - 1.0V. Battery open -> 1 - 2.8V Ground open -> > 4.5V My doubt is if i want to interface to...

    Battery Charging Circuit

    I really liked the circuit and it was simple https://www.ti.com/lit/ds/symlink/lm3420.pdf on page12. I am attaching the circuit, it does not meet my requirements but can i use the concept?

    Battery Charging Circuit

    I need to design a battery charging circuit, the initial study i have done this is what i need to do a charging circuit which i have to come up, circuits for voltage and current feedback. Is my initial understanding correct? This is for Li-Ion battery, if it is 5AH, what are the other...
