Introduction: PURE SINE WAVE INVERTER PROJECT

TECHNICAL SPECIFICATIONS:

VOLTAGE LIMITS (INVERTER MODE) : Mains A.C. Lower Voltage Limit :110+ 5V Lower Recovery Voltage :120+ 5V Mains A.C. Higher Voltage Limit : 275+ 5V Higher Recovery Voltage : 265+ 5V Output Voltage in Inverter Mode : 210V+5%

Step 1: Highlights

1. Full bridge configuration based on power MOSFETs
2. DSP based intelligent control

3. LCD based display for user-friendly display of parameters and status

4. Protection against 440V mains input

5. Protection against reverse polarity

6. Dynamic short circuit protection with fold-back current limiting.

7. Protections against all possible errors like battery low, over load, heavy load, short circuit etc.

8. Early warning for battery low and overload conditions. System continue normally if the error is

corrected.

9. Cutoff and auto restart with permanent cut after 5 consecutive cutoff.

10. SMPS type constant current charger with full charge cutoff.

11. Pure sinewave output resulting in silent operation of motor and fans. Safe to all kind of loads.

12. Ideal for Mixed load application

13. Indigenous design with proven technology.

14. Auto detect of LCD and LED. Can change between LED / LCD while the system is powered.

15. Protection against accidental output feedback disconnection.

Step 2: Design and Transfer the Pcb Design

Step 3: Main Mother Board

Step 4: Design Your H-bridge Board

Step 5: COMBINED BOARD (MOTHER BOARD AND POWER BANK)

Step 6: Finishing and Testing

Hi, it's perfect! but I have a problem, voltage drops from 222v to 178v when 100w load is applied.
I designed a 2000w inverter.
On no load, it gives 222v of which I set it be.
Help on how to resolve this please.

Thanks for all time. I have a problem with feedback. I made a PWM signal with the Arduino MCU. But the voltage drop in proportion to the load. Pleas how can I rectify this. It will be my pleasure having my solution from you. Thanks allot.

Hi thanks for being there always I've done this inverter and its working well but the only problem I ve with it is that I switches off during usage or I increase the load slightly without getting to its peak and its a 12v @ 1.1KVA syatem, please what could be the problem? Please help me out.

Sorry, I missed the low voltage being applied to the bridge circuit. Most of the sine wave inverters I have worked on convert the low voltage DC to about 160VDC for 120V systems. It's more efficient than using the transformer in the output, but the transformer has the advantage of taking out high frequency components.

Also, if you convert to a high voltage, you can use much more efficient IGBT modules that can handle hundreds of amps in one package. Two of them would form the entire power package. One thing I really like about the transformer is that it would make it easy to supply a split phase for powering a home. I am sure there are other, and much less expensive ways than doing this with a transformer. I was looking for a 5KW 120 to 120/120 transformer several years ago and they were hugely expensive. I still have the 5KW inverter, and one day I will use it. Next time I purchase one, it will be 48V in, and split phase 120-0-120 out.

I was wondering where the battery charge circuitry is, and the LVDC to HVDC converter is, in other words, where is the power for the bridges coming from?

What Voltage are the battery's supposed to be then ? I take it its a 2.5Kw Inverter you have made it to connect to a battery bank and a load . Is there any facility to connect to the grid or a grid?

Interesting. Could you post more information about the code and possibly a parts list?
