Abstract
A method and converter topology for ensuring charge and discharge of electric current to a coil so as to allow simultaneous and independent charge and discharge thereof, particularly suitable for a superconducting coil and showing an increase in power transfer by a factor of up to two as compared with prior art converters.
Claims17
A method of charge and discharge of electric current through a superconducting coil so as to allow simultaneous and independent charge and discharge thereof, the method comprising the steps of:
- (a) connecting a power source to the coil via a first switchable path,
- (b) connecting a load to the coil via a second switchable path, and
- (c) selectively switching said first and second switchable path according to whether it is required to charge or discharge the coil independently or to charge and discharge the coil simultaneously.
A converter topology for ensuring charge and discharge of electric current through a superconducting coil so as to allow simultaneous and independent charge and discharge thereof, the converter topology comprising:
- at least two switchable paths coupled to the coil and being respectively connected to a power source and a load,
- control circuit coupled to said switchable paths for selectively switching thereof according to whether it is required to charge or discharge the coil independently or to charge and discharge the coil simultaneously.
