Why is isolation necessary in electronic circuits? How can we implement optical isolation? Gate Drive circuits for controlling switches of H Bridge are discussed and simulated circuit is given.
First the need of dead-band / dead-time is discussed thoroughly and hazards of short-circuiting in H-Bridge are seen. Finally a circuit to implement and generate dead-band / dead-time is given.
Introduction to H Bridge and its working. PWM wave basic concepts and how PWM can be used to operate H Bridges. Ideal simulation of H Bridge in LTSpice (or Multisim) and conclusion to simulation.
