All my projects are free, I design them on EAGLE 6.0. I uploaded it to Google drive. You need to use a web browser to download the file and open the file with winrar software (extract) on the PC. Open schematic file (.SCH) and PCB file (.BRD) with EAGLE software. Hope you enjoy my videos and projects.

Good job regarding the second half of the modification. But the first stage needs modification as it's set to output 270v dc, and you need at least 320v dc to obtain 220v rms ac at the output.

@juliusparker3039 3 года назад

I think feedback or increasing the oscillating frequency should take care of that.

Hello homemade102! Questions: 1) Why do you use FR107 diodes and not 1N4148? 2) Why on the board that you made, the FR107 diodes, are connected to the reverse of what the EG002 datashett shows? 3) In my test of the circuit, I found in the oscilloscope, only PWM signals on pins 8 and 10 of EGS002 = pins 1 and 8 of U1 (IR2110S) = pins 29 and 30 of U2 (EG8010), but I don't have PWM on pins 27 and 28 of U2, not in pins1 and 8 of U3 (IR2110 S) and not in pins 3 and 6 of EGS002? Please, I await your reply! It is very important to me! Thank you very much!! From Argentina.

What i get in this video: 1. We convert to sine wave by applying SPWM to the stage-2 mosfet (what it is called usually? Secondary mosfet? Stage 2?) 2. We dont really need to change frequency of the oscillator or change nunmer of turns of the transformers Am I correct?

@JonathanVaucher 3 года назад

Two questions: 1) Would you still have a decent sine wave under heavy load 1000W ? 2) Can I use this kit on a 110V 60 Hz 1100W (2200W surge) modified sine wave inverter ? Thanks !

Hello, why the VFB feedback (about 2.5V - 2.9V) does not work on the AC output voltage, as it is in most diagrams, that there is a 200k, 10k resistor, 10k potentiometer for voltage threshold adjustment, filtering capacitor. Even the original H-bridge from Aliexpress doesn't work because of this. Only installing a rectifier bridge between one AC output and common ground for everything and adjusting the voltage to about 2.7V gives the effect that the EGS002 does not see overvoltage or too low voltage at the H-bridge output after the 2.5mH-3mH choke and a 2.2uF capacitor / 630V that works approx.

Hello. Great job. I used to convert 2 of my inverters to sine in almost the same way before, but I re-wound the transformers to give a 360 volt dc output. Because the inverter transformer itself was 260 volts. Do you not need to change the secondary trans page wire to do this?

@PhdHung 3 года назад

Yes, exactly, the output DC voltage is 300VDC at 13VDC input, I need to rewind the transformer.

@Reliable_diy_projects 3 года назад

Good project . but you forgot to step up the dc level before H bridge . when you turn a square to sine without changing the dc voltage , effective amount of voltage will decrease . if you put a multimeter after converting it to sine it will show lower voltage than it had before .

@PhdHung 3 года назад

Yes, on the old inverter, the DC voltage was only 260V. I will rewound the pulse transformer to increase the voltage to 380V.

4) I understand that the EGS002 board comes from the factory to operate in SINGLE PHASE !! And because of that, I only have PWM on pins 8 and 10 of the board. How can I enable the PWM on U2 (EG8010) to have modulated signal on pins 27 and 28 of this integrated circuit? I was comparing this board, with a similar one, that uses a PIC instead of the EG8010, but with the same two UR2110S, and I can see that the four signals (pins 3, 5, 8 and 10) have PWM !!! AND IT WORKS PERFECT !!! I await your valuable answer! Thank you very much!!

I have a old mod sine inverter I'd like to do this with, it's a 12v 1200 watt, with good surge capacity, the sine wave hurts some equipment, like transformer in a small radio, and ballast in florescent light, so I do not use it, will this work with a low frequency Inverter? Or UPS? I haven't looked at it, but I'm thinking it may be a push pull, in the UPS, or is this high frequency only driver?

@wernerpeter9706 3 года назад

A modified sine wave inverter has a lower output voltage than a real sine wave inverter. Without rewinding the high-frequency transformers, the efficiency will decrease. Try to reach 220/230 volts AC via the EGS002 and then measure the still possible output power and efficiency (watt input watt output). I would be very interested in a Part 2 with these results from this rebuild.

@PhdHung 3 года назад

Yes, on the old inverter, the DC voltage was only 260V. I will rewound the pulse transformer to increase the voltage to 380V.

@wernerpeter9706 3 года назад

@@PhdHung Why 380 volts? It's a single-phase inverter. To effectively achieve 230 volts, 230 x 1.414 = 325 volts is required at the output. Aren't you wasting too much power in the transformer at 380 volts? Can you test the maximum Watt after rebuild? thx

SINE OR SIGN:- sine:-- the trigonometric function that is equal to the ratio of the side opposite a given angle (in a right-angled triangle) to the hypotenuse. sign:-- an object, quality, or event whose presence or occurrence indicates the probable presence or occurrence of something else.
