摘要:
In a chopper control device in which a magnetic phase shifter is used for providing chopper turn-on and turn-off signals, an external magnetic field is applied to the core of the magnetic phase shifter so as to carry out the notching control of a motor by regulating the residual phase angle of the output of the magnetic phase shifter.
