For Which I Decided to Use a Rectifier to Every Source Converting 220V to 330VDC by Filtering it out using a Capacitor. And Combining all 4x 330V DC in Parallel to get a Common DC BUS Rail. Thereafter I Planned to Use a Tranformerless Inverter Circuit as per Attached to Convert the 330V DC to 220V AC. For which i used IR2110 and 4x IRF840.
As your sources are power limited, voltage /current will drop with load. If the initial voltages are same, they will share current fairly equally. But 220VAC will give only 310VDC; add 1-2 volts of diode drop. You can safely get around 210VAC I presume. It is impossible to debug with the limited information.
But 220VAC will give only 310VDC; add 1-2 volts of diode drop. You can safely get around 210VAC I presume. It is impossible to debug with the limited information. Does it work with one power source? (do not use 4 power sources in parallel in the first attempt)
MULTIPURPOSE: The inverter module can be used as a pure sine , modified sine , single silicon or four silicon pre stage inverter circuit. PRACTICAL ACCESSORY: The inverter board is suitable for DIY production, repair and replacement for electronic hobbyists, as well as for manufacturers'' control cabinets.
