Hello there ,can anyone help me to think on how I can connect 4 MOSFETs(H-bridge )on only two signals of 50Hz for giving AC at 50Hz(I ant this help for designing a DC_AC Converter)

Please help.
 

This is a simplest possible H-bridge, controlled by a single square pulse.

The supply is chopped into AC square waves, which are sent to a step-up transformer.

The low voltage supply makes it convenient, because the transistors need to be biased at the supply V in order for them to operate most efficiently. (This is not necessarily true of the transistor at Q4, which only needs a few volts.)



You can also apply a sinewave bias, to obtain sinewaves at the load. However then you must cope with power loss in the form of dissipated heat.
