The embedded opamp in stm32 foc application working principal

To all expert, I have some confusion about the working mechanism about the current sensing mechanism of the embedded pga. In my sense, foc required at least two sampling of three phase to reconstruct the Idq diagram. With two opamp, I guess it inter...

STPM line and neutral connection

I have used STPM34 In my design. I am measuring voltage and current of single phase supply. Line is connected Pin number 9 of STPM34 and neutral is connected with circuit ground via ferrite bead. check R23 in schematic. I have attached schematicMy...

Hello. I want to use thyristors in electrical Drives (rectifier part). Will there be a problem, if thyristors have been triggered by DC voltage ( that's means : gate's thyristor is always on-state with dc voltage(at reverse bias and forward bias)).

I created the circuit as per simulation in eDesignSuite but unable to get the desired result as its described in the circuit that Iout will be 3A but i am unable to withdraw even 200mA. kinldy help?

BTA16 and ACST10 which is better AC switch for AC Phase cut application?

Hello,We want to design best AC Phase-cut circuit. we have design BTA16 based AC Phase-cut but flickering issue occurred often and also design new AC Phase-Cut circuit with ACST10 which work fine.My query is that which is best AC switch BTA16 or ACST...

¿How to identify authentic TRIAC (BTA41)?

Found a seller whom offers BTA41-600B power TRIAC at lower price than expected, altho they asure those are authentic ​ST semiconductors, i can't permit unexpected behivor from this component for my application. ¿How could I ensure it comes indeed fro...

PM8804 Design Help

I'm looking to use a PM8804 along with PM8805 to produce a 24V, 2.5A POE PD. Are there any application notes available on how to design and calculate components for a forward active clamp converter similar to the schematic in the datasheet. I've look...

I tried to run ihm08m1 using 6 step algorithm , on BLDC Sensorless Motor with Nucleo F401RE Board but motor did not run? I made all arrangements as asked in the datasheet. Please share your valuable views.

Which is the best suitable isolated flyback controller for the input upto 1KVDC and output of 20W ?

I am designing a Isolated Flyback SMPS with input range upto 1KV and output of 20W. I couldn't found any flyback controller which will support this range. I found one offline PWM controller named STCH03 which is having limited 650V start-up.So is it ...

we use your STC3115IJT and your STC3115IAJT. we initialize the STC3115IJT and request the device ID, we got ID = 0x14 we initialize the STC3115IAJT and request the device ID, we got a different ID from 0x14. Isn't the Id have to be the same !?

We expect to got the same ID cause the devices is the same and the only difference is the battery voltages.
