Hi,I am designing 2.7kw boost converter for which I am using SCTW100N65G2AG MOSFET. In the datasheet it lacks information about switching times(like rise time fall time and delays) and max DV/DT the MOSFET can take before failing. I feel these data i...

I am using stm32f334r8 for digital power control. I have configured ADC using cube mx Lower level. ADC reads 0 for 40mv input even though ADC is configured to 12bit and 181 sampling cycles. I also tried calibrating ADC before conversion is started. ...

Hi, I am designing a boost converter based on stw33n60m2, its 2.5kW 420Vout and 250Vin 5 amp Iout. the diode I am using is SIC schottky diode(very less reverse recovary). The issue is that I am facing mosfet failue at around 450v VDS (I dont observe ...

Hi , I am trying to calibrate ADC in STM32334R8. But the code is stoping at calibration phase itself. I will attach the initilization code below for your reference. LL_ADC_Disable(ADC1);LL_GPIO_ResetOutputPin(GPIOC,LL_GPIO_PIN_8);LL_ADC_EnableIntern...

Hi, I am developing digital control for power electronics for which ADC conversion time is critically. In stm32f334r8 reference manual I saw it takes only 0.19us at lowest sampling time i.e 1.5 cycles. when I tried to measure the adc conversion time ...

yaa, I forgot mosfets have parasitic BJT in it. I am young and learning

yaa , there significant around 400ns latency with gpio, which adds up to mesurment error of conversion time. So i wil now trust the manual blindly :beaming_face_with_smiling_eyes:.

vasudev · 2023-11-12

that makes sense but i am using LL functions . will it also cause latency ? wat is the best way to measure the conversion time then ?

vasudev · 2023-11-11

yes the ADC clock input is 72MHZ and also i am using fast adc channel .
