Power management

ı am reading wrong Current value at STC3100. I need help to get right Current Value.

Hi,I attach my Power Side of Project Schematic.I will use STC3100 IC at my circuit. I will use Li-ION AA type Cell in my circuit and I charge my cell externally on charge device. So ı don't use STC3100 while charge status monitoring. I will use STC31...

Why and how is PWM implemented in Field Oriented Control (FOC) ?

Hi everyone, I am trying to understand and implement FOC algorithm in MATLAB for a PMSM. I understand we are converting the 3 phase stator currents into 2 time-invariant stator currents: (direct and quadrature currents or Id and Iq, respectively). Bu...

STEVAL-SPIN3201

Can I use STEVAL-SPIN3201 for control PMSM?

the vn808 device has a wrong datasheet which has a conflict with the app. note (AN2208) regarding to Vin rated voltage, although what should i do with the not connected pins ?

i'm working on a project uses this device (VN808_attached exact photo of the device i have) and in the datasheets carries a name of (VN808CM-32-E) i found in the absolute maximum rating table that Vin max is 5V (attached photo) in the other-hand i fo...

Configuring a 32F303 for motor control (2-shunt method, analog hall feedback)

Greetings All! We have an F303CB processor for use in a motor control application. I wanted to ask on some points regarding the configuration. Using TIM1 with CH1 and CH1N (phase A), CH2 and CH2N (phase B), and CH3 and CH3N (phase C). Switching fr...

STC3115 SOC

Hello,I am using a lithium battery to power my PCB and a stc3115 to have the state of charge. Behind the battery is a LDO to convert the battery voltage to 3.3V, so the voltage of the battery varies between 4.2V and 3.3V. I would like to change the s...

VNQ5050K- E Surge Issue - (what's wrong?)

Dear Community,I'm facing a bad issue on a recent board I designed.The board is supplyed by 12/24V battery and drive some magnetic valves.Unfortunately during precompliance surge test, based on EN 61000-4-5, the VNQ5050K got destroyed and the microco...

STC3100 Reading Current

Hi,I will use STC3100 IC at my circuit. I will use Li-ION AA type Cell in my circuit and I charge my cell externally on charge device. So ı don't use STC3100 while charge status monitoring. I will use STC3100 only monitoring available charge status. ...

Phase current isn't precise at different speed

Hi all,I am using STM32F303RE + IHM08M1 to do a bike project (250W/36V motor).When the motor ramp up, I found the current will output very low and become higher according to speed.I connected a current meter between battery and the board, I found the...
