Your problem is intristing for me. Could you write typical time diagram for gate of Q1,Q2,Q3,Q4 ? The aim of changing direction of motor at 50Hz is torque control or hold position or something else?

Greetings I have a lot of experience in designing electrical systems - specifically those involving H-Bridge DC Motor circuits (as provided) and could come up with a solution to your problem after some initial dialogue with you to more precisely define your requirements. I can either provide an analogue or digital electronics solution (or a combination thereof) in order to assist in limiting costs/provide greater functionality depending on the requirements. I can also do the full electrical design, PCB layout and any associated firmware that might be required if a digital solution is opted for (in order to incorporate additional functionality) and should be able to provide a solution quite quickly. Hope to hear from you soon. Kind regards, David
