Power management

In my 3 phase inverter design i need to increase the current rating. So i decided to parallel the mosfets to attain high current rating. I came across the" paralleling mosfets pfc " and even more datasheet. Is this circuit correct

Using a Viper12 to run leds over 50-1000V range

Hi im struggling with a circuit im designing, im trying to run 3x 24V indicators using a Viper12 circuit. Ive set the circuit up as below:The idea is that the pre circuit introduces the Zeners at 650V, offsetting the input to the Viper circuit by 400...

LED2000DR led driver mcu in which i functioned the circuit for 1.4 Amps. But i got the output only 0.3 Amps only. Output voltage is still 5v But current is very less.

Hi Friends,I have designed a circuit using LED2000DR for a project. I given 5V input to the circuit and i got 5V same as given in the input. The circuit i designed for 1.4 Amps But i got the 0.3Amps only. I am confused that why the current is low. Bu...

Is there any way to contact the STM32 Motor Control Hands-On Workshops organisers?

I recently accepted an invitation to STM32 Motor Control Hands-On Workshops due to take place on 6th Sept 2018 in Copenhagen. Up to this date I haven't received any further information regarding the workshop - location, time etc.Is there any way to c...

Cannot read or write ramp duartion reg

Posted on June 18, 2018 at 12:39Referring to UM1052, chapter 14.I cannot read or write the ramp duration register 0x5C.Anyone having the same problem? ST, is this a known problem/bug????Fredrik#st-mcp #uilibrary

I would like to know what is the current consumption of STSPIN32F0A when it is operated with a 48MHZ crystal.

The data sheet is not specifying this information , Pls. let me know the current consumed by the MCU @ 48MHZ

Current sensing in STEVAL-ESC001V1

HiI got the above board and am trying to understand the current sensing in 3 shunt resistor topology.There seem to be a bunch of C files just for F3xx alone, but only single files for F4xx. Could someone explain which files are relevant for the eval...
