Hello Guys!
Hope you are doing great.
I have taken out a Shell Type Power Inductor form a PSU. I have no information regarding its core type. I have measured the inductance using LCR meter. However i want to test the frequency characteristics of the inductor so i can get idea that will it work...
Hello Guys!
Hope you are doing great.
I am working on feedback of non isolated boost converter. For voltage sensing i am using an ADC. However, the output voltage from the converter has noise. I searched on the Internet and its written that there are two types of noise Common Mode Noise and...
Hello Guys!
I am working on feedback of a Boost Converter (40V to 370V) using microcontroller. For voltage sensing i have employed potential divider technique to lower down the value to 200mV when Vout is 370 which is then to opto isolator (HCP 7800. The driver is linear if Vin is below 200mV)...
I have realised that PCB layout is flawed. I am working on new layout according to post #10. I have one question in mind. Do the power leads (input to boost from power supply and output from iti to the load) needs to be short?. The minimum length i could achieve due to space constraints is 12cm...
Okay guys so i made the PCB and was hoping that distortion willl end but to my surprise the distortion is still there. Distortion at gate was more when Vin was 30 compared to Vin =10 V. I am attaching the scope results for reference. I have used snubber at gate (Grounding resistor and UF4007...
Hello Guys,
Hope you are doing great.
I was looking for a supply for my boost converter with high current capacity and came across an ATX Computer Power supply. I connected the dummy load of 4.7ohms between +5V and GND and on +12V rail i connected a Car Headlight bulb. After turning on the...
How to measure Vgs then if acquired waveform is not actual Vgs?
Also I could'nt get the the avalanche breakdown you talked about. How Vds overvoltage can occur? my input voltage is not greater than 40 V and how faster switching can lead to avalanche breakdown?
Yes the oscilloscope do have USB...
Hello Guys! Hope you are doing great.
I am making a Boost Converter from 40V DC to 370V DC. I previously patched the circuit on breadboard but due to stray inductance and capacitance, i moved to deadbug prototyping (distortion is negligble now). The components i am using are:
Inductor: 1.5mH...
