Hello Dear friends , i am generating six signals shifted from each other .I have done the shifting work and it is working fine .
I am using delay() function for giving those delays or shifts .But i need to vary that delay() generated .I mean i need to generate a variable delay code .I have...
An inverter is connected at the output of rectifier (terminals of capacitor ) and then induction motor is connected at the output of inverter .What should i do for discharging of a big capacitor in rectifier when these arrangement is made .How to protect the diodes of rectifier and the IGBTS...

How can i obtain the peak value ( 310 v) of a 220v rms single phase ,at the output of single phase full wave rectifier ?
Should i use large capacitor ? if yes then what should be the value of that capacitor and its voltage rating and also specify what type of capacitor it should be since it...
You mean that , i should interrupt with 6 times the fundamental frequency .Whenever timer overflows interrupt should be called and executed .what is the purpose of using these interrupts ? Tell me how could i generate these delays in microcontroller ?
How can i generate those phase shifted square waves using microcontroller .The generation of square waves are possible but i am not getting the idea of phase shifting those square waves .Can u suggest any method or algorithm for implementing this phase shifting in microcontroller ?
How could i generate those pwm signals for driving the gates of the switches .I will need three pwm signals for driving the six transistors .Those pwm signals should be phase shifted ,am i right about this statement ?
How can i control the output frequency of three phase inverter using a microncontroller ?
I have heard that pwm is used for controlling the output ? The output of inverter can be simple square wave for simplicity purposes .
Describe any procedure or share any helpful notes , i would be thankful :)
How can i change the frequency of the output of inverter using pwm in microcontroller ? Since VFd is frequency changer than how can pwm changes output signal's frequency using pwm ??Kindly tell me its concept ??

I am trying to make a three phase controlled rectifier using tyristors . How can i control the gates of tyristors ? How to give signals to the gate of a tyristor ?
I have some questions and need some help related to following task .
The task is to communicate a personnel computer and an inverter ( VFD ,used for controlling induction motor speed ) .
My questions are following ,kindly answer me :
1) Which Software should i use for communicating these two...
