The result is that both thyristor and power transistor are appropriate to power supply for radial field coils. There are two ways of power supply with thyristor, they are half-wave power supply and full-wave power supply. There are four ways of power supply with transistor, the first one is switching power supply, the second one is transistor regulator power supply, the third one is carrier waves power supply, and the forth one is transistor converter power supply. Having analyzed the requirement of power supply for radial field
