I have a problem with my circle that the drivers are burned (pin 4 shorter to pin 2) or the drivers are not working properly (HO takes out constant signal regardless of to his entry).
I use in UCC27200 driver.
Can some of the problems were caused because I don’t have delay time between...
I cant find in my capture toggle switch ( on - off - on) .
I searched in folders in orcad Components and i could not find the switch i went.
If somebody please help me find or send me a link to it very help me
I built code converter, the converter I have 4 Trnsistorim, I work at a frequency of 50 KHZ and the varible duty cycle according to formulas ('s very possible that I did something right).
Currently I have a problem that the code is not showing me the frequency and I do not know why -...
I use PWM port that connection to DIGITAL input and from digital input (with interrupt-B5) I take another digital output controller (C0), it's because I need to switch fourth transistors and this technique should work for me.
(Attached picture of the connection)
in duty Cycle I see that I flip...
I am using Pic 16f886. The Pic has two outputs CCP1 & CCP2. But according to the data sheet it has 4 PWM outputs P1A, P1B, P1C and P1D. What are the functionality of P1A-P1D? Can they be used for Duty Cycle and frequency (if yes, how)? My circuit has 4 transistors because I need four outputs of...
hi
i want to know how i using in pwm in controller PIC16F886?
If possible please explain to me about PWM, Like what is it and why need him
If possible Please-give me an example of a program using PWM (I using HIGH-TECH COMPILER)
Thank you ..
Can you please bring me examples of programs (I'm basically doing Converter).
I just want to understand how to use the registers of the ADC?
**I'm using a controller pic 16f886 and HIGH-TECH COMPILER
hi,
1.
I want to know what until which voltage the ADC can measure?
my circuit works between voltages 26V to 52V and I want to know if the ADC knows measure such voltages without making a voltage divider?
* Data sheet does not say obvious - Write high voltage.
2.
Can I please get some...
hi
I have the following formulas(File attachment) to calculate vout/vin in dcm mode on:1. BUCk converter 2. boost converter
First of all I wanted to know how they got them (how developed the equations)
Now my question:
These formulas take into account neglecting losses of the switch I want to...
Thanks, how I calculate the RMS current on mosfet?
Does anyone have formulas to calculate the losses on the switch?
I think that this whole subject will be easy for me to understand through the exercise of the converter at DCM, if someone could please send me it will help me a lot
hi
i need help in buck-boost converter in dcm mode:
1.I want to solve exercises of this converter(in dcm) so I search questions and solutions - because it's easier for me to understand things through exercises , So if someone please could send me it would be nice.
2. How I calculate switching...
