Question

P1. How does H-bridge circuit help in motor functioning? Explain in detail with a circuit diagram. P2. What are the other applications of H-bridge encoder that you can think of? P3. How will the encoder work when a PWM signal is applied? How does the mode of operation change? Consider PWM signal as a regular square wave signal.

Answer 1

H- Bridge the polarity is an electronic cirmit that switches load polarity of a voltage applied to a This H-blidge used in robotics and other applications to move forward and Backward. Thus, Opuation of H- Bridge s- O I vin M Olvin M Vin Vin The H- Bridge is used for reversed the polarity or dilection of the motor as it can used 'brake! as As moving the motor, where motor came to Sudden stop. As motor terminals are shorted. or letting the motor to file Reen. effectively disconnected the circuit. AS the motor from CSScanned with CamScanner

Question 2) the applications of H-bridge:--

The H-bridge is used in robotics and dc motors.

Thus it can used in various toys as well. As it is used to move forward and backwards. Thus motor cars can used this bridge

As the terms I answer first question. Thus hope you understand.. Thank you...
