inverter circuit

Hi everyone, I'm building low power 600w grid following inverter. Scheme is standard with DC-link capacitor at 400v, full bridge H-bridge with 4 power mosfets and LCL filter. LCL filter is designed to filter high switching harmonics. Switching frequency of mosfets is 30kHz and I'm using unipolar...

I am searching details to get parts for repairing a defective inverter circuit, model F606Y8X00AP that is used for Panasonic microwave oven, model NN-P295WF? What are the weakest parts (Rectifier, transistor, IGBT and so on)?

I'm looking for a DIY design for a 20kw pure sine inverter. There are many resources for building 1-3kw versions, but none for an inverter with a 20kw output. If someone has a design they could share or explain to me exactly how to modify one of the smaller inverters to handle the extra power...

The output of the KL MMA 160 inverter igbt arc welding machine is 52 Volts and as it should be. The fan is also working. 4 High-Speed Switching Diodes (1N 4148 5T) diodes exploded on the Transformer Rectifier circuit card of the machine, I replaced them with new ones, but it still does not...

Hi, I'm Nayan and I am working on a project to control the reverse flow of current and voltage of an AC power source from a small inverter circuit. This would be helpful to connect an On-Grid solar inverter to stop the feed-in mechanism to the reference power source to run the inverter in power...
