Wow, my thread is getting crowded.. haha.. sorry for not being around, after i succeed with the gate driver and power circuit currently i am focusing to the control of the inverter..
i will post my latest circuit that work well for me.. i separate the driver circuit and the inverter circuit and...
I tried to simulate with along try it on the breadboard. And yesterday i succeeded to invert 7.4V DC voltage into AC.. Thanks for your help..
The ATmega8535 generating PWM, breadboard circuit of Full Bridge Inverter
Output of the inverter, still in low switching frequency
Output of the...
Hello Tahmid, thx for your response. Actually, i gave up trying with VDD 5v, so i decided to use vdd = 12V and convert my PWM level to 12V with hex buffer (use pull up resistor to 12V) and with those configuration i able to modulate the load supply voltage with PWM from my micro controller.. i'm...
Hello Tahmid, i forget to mention that i have tried it too before (connect the pin 9 to the 5V instead of 12V) but it didn't work. After read your reply and re-reading the datasheet i found this typical connection at the datasheet :
and then i changed the circuit base on your reply and the...
Hello all, last night i tried the IR2110 gate driver with IRF3205 MOSFET and make a half bridge circuit for testing.. here are the schematic for the test circuit :
it goes well when i push on-off the Hin with a switch, the low side MOSFET is always ON so i connected the Lin directly to the...
Thx for your answer, but since this is my final year project i depend on my lecturer decision, and he said to use optocoupler for isolation. But i still don't know what type of optocoupler that could work in high bandwidth and pretty common so i could find it easily on my Country. Is there any...
Thanks for your answer ferdinand, may i know why you recommend me to use isolation transformer instead of optocoupler? is there any problem that i will face if i use the optocoupler? Honestly your suggestion is quiet new for me, i never read this kind of gate driver. Since my deadline is less...
This is my first post here, i need help on my final year project to make a grid connected inverter.
For the full bridge inverter circuit i planned to use IRF2807 (75V Vds, 82A Ids) and Two IR2110 for the driver. I never use IR2110 before and failed many time when i want to make a H-Bridge for...
