Figure 14c shows the induced excitation current by the main magnetic field winding. This plot shows that pulse current pair on each phase stator winding excites field winding.
In comparison with older Ward-Leonard schemes, the majority of dc Mercury-Arc-Rectifier hoists have laminated field windings and a high-speed circuit breaker in the power loop making them ideal for thyristor conversion.
[L.sub.s[sigma]], [L.sub.f[sigma]], [L.sub.D[sigma]], and [L.sub.Q[sigma]] are leakage inductances, respectively, for stator winding, field winding, and orthogonal axis damper winding.
It provides dc power to the field winding of the synchronous machine.
