    Is this Zeta Converter Will work?

    i wanna make zeta converter coupled inductor as MPPT for solar panel 100WP. I read in many article that in zeta converter the switch usually use PMOS. But in this case i want use NMOS using gate driver IR2101 High Side driver only (not synchronus converter). In simulation the circuit is...

    Need datasheet for Murata CD1450C module

    I'm currently working with a DC-DC converter labeled as CD1450C. We have industrial power supply that has this component. Dimension is 50x50 mm. But I am unable to find its datasheet or detailed specifications. The one I have is damaged and I need to replace with an equivalent one. I know it's...

    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...

    R/S flip flop usage in DC/DC converters

    Hi Everyone, Can anybody explain why R/S flip flop is used in this circuit? I would also like to know how the clock signal should look like in duty cycle? Last but not least, in R/S flip flop's truth table, it's stated that both set and reset pins shouldn't be turned to high state at the same...

    How to use of GaN Transistor gates instead of IGBT in this circuit ?

    I have a boost converter circuit. its designed with IGBT . But I wanna use GaN transistor and simulate it . But GaN Transistor has two gates . Do I have to use two gates or using one gate is enough ? How can it be its design with vpulse values and resistor? I added photo of circuit, GaN...

    How to Choose Best 650 V , 60A GaN Transistors for Switching Losses ?

    Hi , I will calculate GaN transistors switching losses in Dc DC converter Systems. The formula is , Psw= Vds*Id*fsw*((Ton+Toff)/2) . Vds and Id are drain-source voltage and drain current of the device at OFF and ON intervals respectively. fsw switching frequency and Ton is switching time...

    How to get correct graph in this Pspice circuit when simulate it ?

    Hi I am studying a dc dc converter model. My friend drew this circuit and got this graphic. I added his circuit and graph . But I draw same model , same numbers for resistors capacitors v pulse source ,inductor, diode but my graph is very different. Actually my V pulse source looks like doesn't...
