Static traction/braking switch-over circuit for a variable speed system including an asynchronous motor powered by current switching |
摘要 |
A thyristor (TR) is used to switch over between traction and braking states. Rather than supply a special extinction circuit for the switch-over thyristor, it is connected to make use of the extinction circuit already provided in the chopper circuit (H).
