Finding issues with STP45N65M used in a 500 kHz HB LLC Resonant Converter

Hi We are using a  STP45N65M for a 500 W HB LLC operated at a frequency varying from 250 kHz to 500 kHz. We are using a driver SI8273 ( 4 A Isolated driver) with a Rg of 2 ohms. We are facing the following issues.We were not able to get a rise time ...

STPM34 Active Power and Power Consumption Issues

Hi guys,I'm using STPM34 ASSP IC and get some issues. Hope you can give me a help. I followed it documents and recommend design.I’m trying to use your evaluation firmware in order to interfaces with STPM34 by using an external MCU (STM32F15) through ...

BLDC Error FOC with ST Motor Control Workbench

Greeting!First of all I'm quite new and not really familiar with the STM products.I want to control a BLDC motor (Turnigy Multistar 4225-390Kv 16Pole) with the Steval-spin3201.When I connect the ST MotorControl Workbench with the eval-board and press...

Hello , i have the ic spv1040 , and I have one problem in my design : The integrated circuit supports from datasheet around 5.5V input , but my solar panel have around 6.5V (Maximum power 1W) in full sunny day .

How can i manage this ? Does the circuit sustain voltages in range of 5.5-6.5 ? I need an extra electronic circuit for ic to work properly ?

Figure 8 in the data sheet for part number STUSB4710 shows the inductor value to be 68µH. This seems large. Is it possible this should be 6.8µH?

Detailed Specification of the buck converter in STSPIN32F0/F0A?

Hi, guysI am the newbee in using stspin32f0, so i had a question on buck converter which is integrated in it.​Since i use a 10uH inductor (typical value is 22uH in the AN5128), VDDA will shutdown when VM=18v~20v.And, after replace it with two seri...

How to find current from battery side ( not motor current ) foc sdk bldc 3 shunt resistor

Hello dear STM community family,I have been trying to develop bldc motor controller for some weeksIn motor control sdk, I want to use 3 shunt current sensing method.I don't want to add shunt resistor more in hardware to read battery current.Could any...

Hello, please give a pdf manual for APIC-S03 HSSOP36 (analog E-L9728TR) and for APIC-D06. I can not find it. Thank you!

Hi all, We are new here. We are thinking of using ST L6203 motor drivers on our robots and are wondering if it is recommend to control motor speed by PWN on the enable pin or is better to PWN either IN1 or IN2 depending on direction.

http://users.ece.utexas.edu/~valvano/Datasheets/L6203.pdf We've had quiet a discussion about this and it would be great to know which method is preferred.CheersTerry

Opto-coupler for L6470 ?

Posted on May 21, 2018 at 16:33It is necessary to apply a opto-coupler between an SPI Master and the L6470 circuit on the X-NUCLEO-IHM02A1 board ? I could not find any information about galvanic isolation in L6470 documentation.#x-nucleo-ihm02a1 #op...
