full bridge rectifier using mosfets

HI all
i am working on input bridge rectifier based on mosfets i need some help in switching timings of mosfets

Re: full bridge rectifier using mosfets

i am assuming that your aim is to rectify 50Hz supply, now the time period is 1/50 = 20ms , means 10ms is the duration of half cycle so you have to switch your MOSfet @10ms with proper deadtime .

Ya but i have to manage two mosfets for one cycle i was trying to switch but i am getting some shoot through currents how can i avoid them



my circuit looks in this way .............

You didn't visualize the gate waveforms. The timing doesn't look right.
