These circuits are often used in robotics for starting DC motors forwards and backwards. Constructive Solutions schemes may be different, but they have a common principle H-bridge has four key ( switch relay , transistor , thyristor , etc.) , labeled in the figure S1, S2, S3, S4. States may have different key combinations , practically significant are the following :
