the diode you are using is not recommended for high frequency, try to use a high frequency diode like mur460 or her408, if you use a bridge diode as in the video it will usually heat up quickly and break easily and is recommended for low frequency. and if the circuit works at 20watt even without load try to add a 20k potentiometer on pin 6 ic sg3525, then try to connect it to the power supply, then rotate the potentiometer until you get the lowest standby amperage, usually the problem occurs in the mismatching of the transformer and pwm frequency, pin6 on the sg3525 ic to adjust the frequency, and it could also be a problem with the high voltage 300v output diode, try using an ultrafast diode.

You are absolutely right. I made this inverter according to this project and in fact: in the idle state it consumes quite a large current and it had to be corrected, secondly, Shotky diodes had to be used in the rectifier. Not to mention the routing of paths and the unfortunate location of other elements... especially when it comes to large capacitors. If someone thinks that they will run this system without much knowledge, they can seriously miss the point

Nicely done. As digital board designers we tend to think of a trace as a line from point to point. (5mil here) However if you look at analog boards, and especially audio, those PCB designers seem to take the opposite approach and create isolated islands, leaving as much copper as is possible. So they simply create design rules mandating clearance and "flood" the plane as much as possible. This of course gives you more current capacity. The boards conduct heat better and will etch faster. Surface Mount technology originated in Audio/Visual markets where single sided boards were dominant An all SMT board needs no drilling or vias. Just mentioning this because there are many ways to do something right and its a fun exercise to consider the options.

I've made an inverter few months ago based on the same ship, the most challenging part to me was the inductor filter, I struggled alot to find the right material core (it has to be a low permeability core), adding to that I had to reach around 3.3mH inductance, but after 80 turns I almost had no window area left to add more turns and I only got 1.2mH, So I had to compensate that with a higher output capacitor !

I took a look at the schematics and... I think that the bridge rectifier is not rated for high frequency, that may explain the low efficiency at light loads, and may cause catastrophic failure at higher loads.... The ideal is to use fast recovery diodes... And for 500w, that shunt resistor will do nothing I think... The voltage drop the egs002 board detect is 0,5v I think, and for 500w 0,25 ohms should be enough for 2amps overload at the output

Yes, these are kinda nice but watch the bootstrap voltage on the gate drivers. I blown many ir2110 and mosfets before I scoped the gate drivers power rails. My inverters were randomly blowing when idle or at power-off. I was deep in the dead-time settings but missed the fact that the gate drivers were ringing like mad and spiking to 18v regularly. Lowering the esr on the bootstrap cap did the best in lowering the ringing amplitude. Zenners are the last frontier. My measurements shown 30-40ns long spikes...

A trick that will not need a redesign is to mount the IGBT's and other fets under the board so that you can mount to a Heatsink like an amp or some of the grid tie inverters this will allow more room for heat sink thus better cooling as those caps behind the IGBT's are in the way, but other then that very clean board.

couple of red flags: 1. Mosfets have no heat sink, at least add some thermal compound before adding the heat sink... 2. You dont mention the switching frequency of the DC-DC stage 3. It would be better if you picked a different mosfet instead of having two of the mosfets operate in parallel 4. It is better in this case when each mosfet has its own gate resistor instead of having one gate resistor for two mosfets. You have to check if the SG3525 has enough gate driving capability. 5. You didnt show us the VDS/ Vgs and the current through the mosfet waveforms on the oscilloscope 6. There are no bleeders for the high voltage caps, it is so dumb to mention to always discharge the caps when you can just add two-three bleeder resistors to your design 7. The HV HF stage is called a push pull converter atleast do some research please 8. There is no proof that the HV HF transformer is not saturating, show the current through the mosfets and transformer when you publish such projects. Last thing you want is saturation... 9. Who knows how the transformer is wound, if there is sufficient isolation between the primary and secondary, if primary/ secondary has to be wound with litz winding to reduce skin affect ? 10. Your schematic/ layout doesnt show the dots of the transformer... 11. You dont have detailed information on efficiency of the DC-DC stage and DC-AC stage 12. Maybe SiC transistors would be a better choice than IGBTs... 13. it is better to add a solder mask to reduce exposure to high voltage tracks ? 14. NTC has to go on the heat sink or at least close the mosfets or IGBTs not somewhere willy nilly on the PCBA... 15. Mosfets have no pull downs

Pretty cool project, there is a lot of room for improvement! I myself am starting a video series on inverters and my first video in this series is live! 📺 Use a better transformer, and a smaller one to minimize losses, run at even higher switching frequency with really good silicon or possibly even something like GaN Use a split secondary output to implement a full wave converter rather than full bridge, minimize saturation voltage drop losses of IGBTs, or use GaN or SiC to further reduce losses Use synchronous rectification on the HVDC generation stage, to eliminate losses from a traditional diode bridge. Don't have the capacitors butted right up against the full bridge rectifier and transformer, these components get hot Heatsinking looks like more of an afterthought

The layout issue was those two 100n caps BEHIND the inverting H-Bridge MOSFETS making it difficult to get a good solid heatsink mounted there, if you move those to the front or put them underneath, then a heatsink can be mounted to both the boaed and FETs. Don,t forget the sil pad to isola te the backs of the FETs from the heatsink. Cheers fron Tasmania!

Frequency is easy to change. For the voltage, you would need to supply the IGBT bridge with 220V instead of 380V. That's why the transformer has 2 outputs. But you will need to change the PCB so the 220V is connected to the IGBT instead of 380V. I haven't tested this yet so this is only a recomendation. Have that in mind!

Second question is about capacitors used for the first stage, you used 450v 100 uf capacitor. Can we use same capacitor that you used in coil gun project, the fat 450v 680uf one?? I just have few of them around😊. Thank you again for this wonderful project

How can we modify your schematic for 24 or 36 or 48vdc as input?

Yes, the best thing to do is just use a buck converter to step it down to 12V or a linear voltage regulator. If you want to use higher voltages for the input then you might have to alter most of the circuit.

The power is not wasted the igbt internal capacitor use 29 milliamperes a not load and 40 milliamperes loaded and the more the load increase the higher the capacitor charge get to it will go up to 70 milliamperes per igbt

Could you increase output power by using higher voltage battery so you don't need that high of current. I have many 72v batteries but there aren't many inverters for them available.

Great project! Could you please make a video in which you explain about the working of this circuit, boost section waveforms on load, and output section LC filter design with respect to frequency. Thanks for the video❤.

I have actually designed the booster section of the inverter which was capable of 250w but the output voltage drops when i put the load on it from 230v to 170v even with regulation feature of sg3525. If you can please make a video about this topic. Thanks

Many thanks for your video Please, what is the difference between SG3525 inverter and CD4047 inverter for performance and efficiency ? Also is IRFP250 mosfet is good for inverter or which one your prefer ?

Well the IRFP250 is quite a good MOSFET for most applications but keep in mind the voltage and current rating of the component. That can be found in its datasheet.

Thank you very much for this educative video. I want to build the exact same circuit using your provided files but first, I want to verify the parameters of the shunts you used.
