After referring many forums and sites i designed a circuit for my application. I am getting output as i expected for 12v dc motor as load and also getting output for bulb by using 110v as supply. But, problems occurs while trying 220v dc the low side part of bridge gets damaged.
Note: I am...
I am posting my requirements in the form of rough block diagram.
I have a control device in which two control buttons are placed. There are 2 output terminals. Each output has two pins i.e (one output has two pins). The two pins are shorted when pressing control button in the front panel of...
I referred the above links in which four pwm signals are generated by the controller and they are given to ir2110 driver circuit for generating a sine wave. I need those signals to be controlled by a input from my another device. Is it possible to place a relay in between the controller output...
Hi mitra,
Is there any tutorials or threads in this forum regarding this process. I am not able to figure out the things you have mentioned in previous comment. I am planning to use 4/8 MHZ crystal oscillator for pic, and what is operation frequency at the driver input and array of pwm widths...
I am going to use PIC16F877A microcontroller. But, i dont know how to generate pwm signals using microcontroller.
Kindly provide me the guidelines for generating the pwm signal using the PIC microcontroller for the switching operation.
Then my question is how to generate those pwm signals for controlling the switching. Using pwm ic's or using micro controller. I want to know how to generate those signals for controlling the switching operation.
My task is to provide the voltage from the cap bank to load by using two control...
I am asking whether the HIN and LIN signals can be given as 12v dc or not.
Giving 12v to LIN to switch on the Q2 which charges the Cboot by providing ground to Cboot.
Then giving 12v to HIN to switch the high side transistor. Same for the Q3 and q4.
If is is not possible can you explain me...
Hi Klaus,
Are you saying that if i remove that resistor the circuit will work fine.
I have one more doubt it is mentioned in all the threads and forums that the low side switched ON once in order to charge the bootstrap capacitor Cboot. But, in H bridge the transistor Q1 and Q4 are switched ON...
Hi,
I have gone through many designs in this forum and found IR2110 is used as driver ic. But when i tried the half bridge circuit the Cboot gets charged when the low side switch is on but the charge gets discharged immediately. So, i couldnt get the output for the high side switching.
I...
I need to switch 230v dc supply from the capacitor bank to load in clock wise and anti-clockwise direction (when the q1 and q3 igbts are ON the load should get +230v and when the q2 and q4 gbts are ON the load should get -230v from the capacitor bank).
The IGBT i am going to use is G160N60. I...
The problem is solved in mplabx ide and xc8 compiler.....
While compiling the code in xc8 compilere there are no spurious transition errors in proteus..
i am using hightech c pro for the PIC18 family v9.65 and MPLAB v.8.56
