Sine wave power inverter

[batee]

Hi,

Can anybody provide me schematic diagram of output stage of HalfBridge as could not found application for dual voltage tapping +/- since the gate voltage should not exceed to say 20 V w.r.t. source of lower side Mosfet/IGBT. This can be achieved by using Bridge driver IC, but I could not find any practical application for it, however a separate bridge driver like TLP250 can be used but practically I have not yet used. Is anybody enlight/share on this with their experience.

IR2184 is a high side AND low side driver. It generates the extra 10-15V needed above the bridge supply voltage to turn on the top FET, and gets you dead time protection and logic-level inputs, too. It's good for up to 600V, unlike every other FET bridge driver I saw. Two are needed for full bridge operation. If you need programmable deadtime, use the 21844.

Half-bridge schematic is included in the datasheet.

Good luck,
