I have made the multiphase buck converter.I tried testing it, but when i connect the input supply to it the supply reduces to some 2.4 from 12V.What is the reason for this ?

This was done at no load.
I am trying to sense the inductor current in this circuit. I used the lm741 opamp in differential amplifier configuration.The sense voltage is 50m*12. where 12A is the load current.From my design i should get a output voltage of 3V but i get 2V. And if i connect a resistor to the output of the...
I implemented them but by mistake skipped the end of the code
rk2=rk1;
rk1=rk;
M1=(-b1*rk1)-(b2*rk2);
M2=(a1*rk1)+(a2*rk2);
could you tell me more on this, the variable types, parameter scaling aspects
some reference will be good
I have implemented a digital pid as a second order module based on the following equations
ek = sk - yk; /* Calculate error term */
rk = ek + M1;
uk = a0*rk + M2; /* Calculate output */
rk 2 = rk 1; /* Update variables */
rk 1 = rk;
M1 = -b1*rk 1 - b2*rk 2;
M2 = a1*rk 1 + a2*rk 2;
based on this...
I followed a application note from ti to design a 2p2z controller. Mapped the s domain controller to z domain, but found that the bode plots of the z domain and s domain controller are not similar. so i checked the bode plots of the controllers on the application note and they are also not...
Is this tuning i am trying to do correct. To the response of post #5 i tried to tune it.
When i increase kp i see improvements in rise time and settling time while i get a steady state error. I tried increasing kp further and the output never starts to oscillate.
when i introduced Ki the steady...
Does this system require any kind of controller ? As there is no steady state error and also the rise time is considerably fast.
This is the step response of the output filter of a buck converter
Could someone provide some help to make this system stable
I have attached the bode plot of the closed loop system. I have also attached the matlab script i used to generate the bode plots along with the transfer functions used for the same ?
What changes should i go for ? bandwidth/...
Hello
I designed a type III compensator based on a excel sheet provided by sipex. I then plotted the closed loop bode plot for my entire system.
What i saw is that as i change the position of the first zero of the compensator the phase margin changes, but not linearly.As i place the first zero...
Are the light green spots on the pcb the connectors ? Is it single sided ?
Sorry kapil for not being precise on the first instance. could you incorporate certain changes here
There is only one smd capacitor C1 (C1 from layout). Other caps are not smd they are through hole, also the resistors...
