The H-Bridge Motor Driver Circuit . This circuit is called H-bridge because the MOSFETs form the two vertical strokes and the motor forms the horizontal stroke of the alphabet ‘H’. It is the simple ...

For example, motors which are used in toys (car, bus etc), will move forward in case of +12V and it will move reverse in case of -12V. We have shown the motor rotation in both the directions, using ...

The contacts that start and stop the motor are physically located inside of the starter. They are depicted with M1 symbols in the upper right of the Figure (line reference numbers 101, 102, and 103).

D4, D5, D6, and D7 3 are used to suppress the DC motor’s reverse current spikes. Internal reverse Schottky diodes have been embedded in the MOSFETs; however, using these external Schottky diodes ...

Typical magnetic motor starters that are commonly available include: full voltage (across-the-line), reduced voltage, and reversing. As the name implies, a full-voltage or across-the-line magnetic ...

Fast- switching reverse-conducting thyristors have been developed and used in dc chopper apparatus to control the speed of highvoltage dc traction motors. The newly developed dc chopper circuit and ...
