    Buzzing noise in the speaker

    Hello everyone. I am working on a project where I use raspberry pi and a speaker. I'm using an amplifier module for the speaker which operates on 12v while raspberry pi needs 5v hence I use CA-1235 DC-DC converter which converts 12v to 5v for the raspberry pi. Now, I can hear buzzing noise in...

    Voltage Divider VS Op-Amp Feedback in Push Pull Converters

    Hi, in High Frequency Inverters, Voltage is First Boosted to 311 VDC using push pull converters, then it converter to AC using SPWM and couple MOSFETs or IGBTs. to maintain the 311VDC, the PWM IC such as SG3525 is getting feedback from the rectified voltage which is the 311VDC. The point is...

    DC-DC Boost Converter Switching Frequency

    hi guys, currently i'm want to design a dc-dc boost converter but i don't know what is the best frequency value that i need to use in this converter. can someone advise how to find the best pwm switching frequency? i need a justification why i supposed to use that frequency value on my design.

    Non inverting DC-DC converter that makes fix 4V from a decreasing voltage from 4,2V to 2,8V?

    Hi! Is it possible to make a a non inverting DC-DC converter that makes a fix 4V from a Li-ion battery's voltage. I need about 1,5A. The input voltage starts from 4,2V and decreasing to 2,8V as the battery discharging.

    Difference between converter input impedance and transfer functions

    I am doing some work trying to derive the transfer function of a resonant LCC power supply. I have come across analysis online which shows the derivation of the input impedance of the converter, which I have attached. My question is a basic one which may sound stupid, but i've not much...
