hi everyone
i am building a simple DC-AC inverter for my school project, i am stucked at how to use a 555 timer to generate control signals to control two MOSFET, which will output ON/OFF/OFF to one MOSFET and OFF/OFF/ON to the other MOSFET, is there a simple logic circuit to do the job? ideas?
thanks
Doesn't sound reasonable. 4027 and 555 have delays in < 1us range, even the comparator response time is much faster than the delays viewn in your waveform. The circuit must be different from the above suggestion somehow. I would expect a small delay of the comparator output, it may be necessary to apply a correction (e.g. 555 discharge resistor) to avoid a very short pulse at the ramp start.i asked the tutor he said its the delay of the 555timer and flip-flop. that caused the phase shift between flip-flop output and comparator output.
