Hello friends
I have two types of iron to make the iron core Transformator
In the same number of rounds
220v to 12V
Type A No Load current = 130ma
Type B No Load Current = 100ma
What can we conclude empirically?
Is Type B Better?
Thanks
this is my code ( In conceptual terms )
buffer[x]>>=4; /* Skip 4bit LSB */
buffer[x] = buffer[x]^0x800; /* Convert Unsigned to Signed */
Dac_Register(12bitLeftAligned) = buffer[x];
but not working and have very bad voice
Please help friends who have experience in this area
Hello friends good time,
I easily play 8bit wav file using DAC in STM32
But when play 16bit wav Anomalous sounds can be heard
tested several sample rate 8k,16k,32kThey all had anomalous sounds
I use the dac 12bit right alignment
MCU Clock 48MHZ
Read Data From MicroSD
in system that play...
Hi friends a question
Usually the shunt resistor has an inductance value
I want to identify the short circuit by shunt resistance
How can I ignore the inductance effect of shunt resistance ?
thank you
So with a quick opamp. I need to detect overcurrent and and turn off IGBTs ( Regardless soft turn off )
One question is, how do I determine if the spike is passing or is the short circuit ?
We only have shunt resistor opamp and a Vref for detect over Current
Hi friends
In an inverter I want to cut the gate signal in short circuits
i using STM32F103
The problem I have is the short-circuit tolerance time is about 5-10 microseconds
How can I quickly detect the current ?
High-speed sensors are very expensive
if i using HCPL-7800 and shunt resistor...
hello friends
i have a capacitor charged with 812 V DC
in under this capacitor have a heatsink
how mush i have to Spacing Between PCB PAD and heatsink ?
Humidity max 70%
Temperature max 80 degrees
An image similar to what I need
Thanks a lot,
Hello friends
Is there a way to detect the ferrite ring power without the datasheet?
I have a green ring ferrite
inner diameter = 37mm
External diameter = 63mm
Height = 25mm
Thanks a lot
Hello Friends ,
i want drive a mosfet in 10khz PWM 10v 2A IRFP240
i should use IR drivers series or i can make simple driver with BJT PNP NPN ?
What is the advantage of a gate driver over this circuit?
i don't need isolation
*Values are incorrect and not calculated
Thanks a lot
Dear friends hi
I am designing IRON-CORE TRANSFORMER
Step Up
Vin = 24V
Vout = 220V
Ferq = 50HZ
Power = 500Watt
What is the general rule for calculating no load Current ?
is this true if i set the no load current high i can get a better momentary Current at Output ?
Generally, if i...
Hello friends
if i short circuit VCC and GND Micro burn . any Micro
VCC = 3.3V
using LM2596 3.3V .
LM2596 Schematic :
how can i Protection micro from this ?
hello every one
if my 12v to 220v converter using Boost topology and have no isolation .
Whether this is contrary to standard?
Not isolated, what problems may be the cause In a boost converter ?
Thank you
