hysteresis controller?

[shahulengg]

Can anyone help me to design hysteresis controller. the input signals to the controller are non-sinusoidal high frequency signal. the output of controller is the required gating pulse for MOSFET fed single phase inverter.

Hysteresis control is used in a schmitt trigger. They are discussed in this recent thread:

sir actually i am trying to make hysteresis controller using analog circuits. could you provide me any suggestions regarding that too.

The thread I referred to contains a post with a diagram, which shows a generic method for creating hysteresis using an op amp.
