Dear DeepOne
This diagram, given the sine wave or the square wave? If I replace IRF3205 by IRF840, can I raise the voltage from 36VDC to 320VDC?
Do you have a version that uses Atmega8?
Thank you!
I do not have enough 50n03 should have been replaced by 50n06, but it broke down immediately after the power supply. Maybe, two different types of Mosfet parameters: Turn-on / off delay time, Rise / Fall Time. So 50n03 replaced by IRF3205 ok or not?
In diagram # 463, I want to raise the voltage...
Dear DeepOne!
I am testing in item # 458 but had little trouble as follows:
- This is my memory in the data set before programming.
- When programming the error, as shown below.
- I read back then noticed a little difference and marked as in Fig.
I do not know why this happened, I do not know...
The good news: The circuit has worked well, I have found the cause USBASP connect to MCU wrong as shown in Fig.
By the way, you can tell me what is the name of the software that you use to draw the diagram. I look at it nice and clear and want to use it.
Thank you & good wishes.
Thank you for your reply soon!
I chose the correct frequency is 16MHz quartz, on my proteus simulation file also choose 16Mhz.hex.
pin Ain1 connection 1k resistor then to the terminal D of mosfet against polar opposite. When mosfet open, the Vds this mosfet will be very small, I thought it...
I've assembled a diagrammatic # 463 but it did not work. Electric current measured before pressing RUN is 0.16A DC. After I review the attached simulation files, I have found the problem:
When I activate the overload protection function (press the button to ain1 = 0 vdc) but I understand that it...
Dear DeepOne!
I'm in the process of circuit layout post # 458 and # 463 for assembly. But I have a few more questions to ask you as follows:
# 458:
We can use many types of quartz (12-16MHz) without having to change the firmware?
# 463:
We can use different types of MCU Atmega8a-pu...
According to your guidance, I checked PB 3 = 4.5v, but it did not work. Then I connect PB3 and PB2 to Vdd = 4.8V, but it also does not change.
I have reloaded firmware mode "Read out protection OFF" under the Option byte. Bulbs do load was light, but less than 1 sec two mosfet source controlled...
I have assembled as # 373, when loaded firmware software complete notification, but when I connect the 310VDC power supply, circuit does not work. Check with oscilloscope, there is no output pulse. Viper22 circuit is ok. 18.4VDC for drivers, and 4.8VDC for the MCU.
I'll have how to check ? There...
Dear DeepOne
I tested with # 423 (IR2304 with totem pole) is pretty good match. Waveform, as shown below:
But I tested with # 419 (IR2103 with no totem pole), the wave is distorted as shown below.
See distortion, I mounted totem pole to the circuit IR2103, but destroyed mosfet. The circuit...
Dear DeepOne!
Please help me find the reason why it does not work at the driver. I use the oscilloscope to check the pulse signal from MCU is well.
Thank you!
Dear DeepOne!
The type of transformer used is what type? ferrite core or steel core. Look at the frequency, I think that is a ferrite core. It is also possible to use both 2 kind?
Thank you!
