Hello, We are going to develop a 3 phase interleaved PFC for 30kW. I want to apply STNRGPF01, but it is marked as NRND. I wonder if there is any reason why it should not be used or discontinued.
If there is a clear reason for not being used, can you recommend another part?We can't do fully digital programming.
Resolved! How to drive the BOOT pins of a STSPIN32F0251?
I have an EVSPIN32F02Q1S1 board to experiment. Each boot pin has a connection to Vcc via a diode (D1, D4, D7) - which are not mounted on the board. When driving a phase full on the pull up MOSFET breaks down about every 2.5ms. The time varies dependi...
H2PAK-2 vs H2PAK-6 MOSFET package for high current application
I'm using multiple MOSFET of STH310N10F7 in parallel for current of approximately 60A.MOSFET are used in DC Bias and not switching so time delay is not a factor of consideration.I'm confused between the packages.What are intended application of H2PAK...
Beginners question: IHM01A1 + Stepper - What am I doing wrong
I am an owner of the STEVAL-EDUKIT, an inverted pendulum kit by ST with an NUCLEO-F401RE, IHM01A1, Nema17 motor and an rotary encoder + a 2A, 12V power supply. I have no prior experience with motor control whatsoever. See https://www.st.com/content/s...
Which pin is used as output for connecting load on spv1050 ? i need to connect load .
i am trying to charge li ion battery. the power should be available all the time , even if there is no harvesting in process.#Spv1050
IHM01A1 Shield project - How to create from scratch?
I am using a IHM01A1 Stepper motor shield with an STM32F401. The provided example for one motor from the X-CUBE-SPN1 package works as expected and I can properly control the motor.Now I want to basically recreate the project from scratch as a prober ...
Resolved! IGBT gate resistance value calculation.
Q1. How to calculate IGBT gate resistance.I want to use STGD18N40LZ IGBT for operating an inductive switching load. Switching freq:- Between 400Hz to 1KhzCollector to Emitter voltage:- 24V.Avg Max current :- 5A.Q2. What will be impact If I use 1Kohm ...
Resolved! high input voltage into an L7805 - would like to add a resistor to drop Vin, but not sure how to calculate
In the datasheet, it gives a formula, R = (Vi(min)-Vxx -Vdrop(max)) / (IO(max)+Id(max))My IO is 0.1A, My output voltage is 5V. My input is currently 24V. I saw some discussion that I think I should consider the Vdrop to be 7V. Is Vxx the voltage I...
