Dear all,
This a question regarding a regulation of DC/DC converter, I am trying to use PI controller to help tracking the output error to zero.
By comparing the open loop and the closed loop diagram, it does not seem like their will be any oscillation at any point, so I am not sure where to...
Basically, The output voltage will be changed by duty cycle, anyway the project will run over a wide range of temperature, so any deviation in resonance frequency will drop the output voltage, what I am seeking here is a regulation of the output voltage, and specially locking the resonance...
Hello,
I am working in my thesis on optimization of resonance DC/DC converter, the input voltage is 10V and the output voltage is 5KV (voltage multiplier is used), almost no current at the output.
The working principle is based on the resonance of the transformer. Somehow, when I increase or...
Thanks horace1,
This is working for me, actually I am using this as a part of my code for a microcontroller, the for loop variable is used as an index for an array in a restrict timing regulation, anyway when the value reaches 10 I can reset it then in an other part.
if (cnt!=0 && Error<0)
{...
Hello,
I would like to know is there a way to to return back to the last iteration of the for loop, after the break and continue from there, for ex.:
void loop()
{for (n ; n<10; n++)
if (n=5) {break;}}
//code lines
//code lines...
Hi again,
Is this the so called "PWM Dithering"?
I have 16MHz clock, 200KHz PWM frequency, 6 bits duty cycle resolution.
Do you think it is practically possible to add extra 6 bits by this method?
Regards,
AAOAA
Hello,
Actually Duty cycle range 0-50% and less than 0.1 step is necessary, the frequency should be fixed around 200KHz at resonance. I dont think that "burst mode PWM" is useful in our case. Could you please tell me how to modulate LSB or how to realize it on MSP430?
AAOAA
Thank you for your reply.
Actually, I am working in my thesis on optimization of resonance DC/DC converter for space application, the input voltage is 10V and the output voltage is 5KV (voltage multiplier is used), almost no current at the output. The PID controller should have a fine tuning...
Dear all,
I am limited to this microcontroller: MSP430I2020. It has 16MHz clock, 16bit timer. I need it for controlling a switch at a frequency of 200KHz, probably in this case I will have around 1% Duty cycle step and I need at least 0.01%. Does anyone have a solution?
Thanks in advance.
Hello,
Actually, I am working on a SMPS that is used for research purposes 10V input, 5000V output almost 0A output current, the lowest possible power dissipation is required.
My interest here is about core losses. The equation that is given in the Master datasheet (nomograms are not in the...
Hello,
I am using LT1037, I used Rf1=200K, Rf2=100 as feedback resistors which equals to 2000 gain, but what I am getting is only 600!!
could someone give me an explanation for this?
Thanks
