hi,
I have use UF4007 to charge bootstrap capacitor and also follow Tahmid's idea but i do't get pules at high side driver output. plz suggest me any other sch to check IR2214 IC. i have dead line to complete this project "Full bridge converter" and i tried it lot.... plz help me...
Thanks Tahmid,
yes i have use oscilloscope to check the high side output. pules are not obtain at high side but low side gate of IGBT with respect to GND it appears.
Hi,
i have problem in ir 2214 high voltage gate driver. i have made driver circuit as par the datasheet,but output of the driver at the H bridge( H bridge configuration made by IGBT GT20J101) working only at the low side and output at high side not obtain. frequency of PWM is 25Khz.
Ihave...
Hello,
Thanks for your suggestion but i have one more query.
V to F converter (lm331) generates output in the range ( 0 to 0.6V ), when motor will run from low to high speed. 0 to 0.6V range is set by preset R9. If will reduce voltage range from (0 to 0.6V) to (0 to 0.1V) then it will work as...
Dear Sir/Madam,
I have problem in speed control of DC shunt motor chopper circuit. My motor is working fine when i connect it in open loop configuration by varying the armature voltage (armature voltage is varied by varying duty cycle) but when i connect the motor in closed loop system, the...
