Abstract
In a power supply for use with electronic equipment, the power supply includes a dynamic transformer having a single rotary element with permanent magnets attached, magnetic bearings to support the rotary element during operation, primary and secondary windings linking the flux of the magnets, circuit means to drive the primary windings, and means of using the secondary AC output to provide DC power at the point of use.
Claims24
A dynamic transformer for converting a source of AC or DC input power to AC or DC output power for use in electronic equipment, said dynamic transformer comprising:
- a primary winding;
- a secondary winding, physically separated from the primary winding and having no electromagnetic coupling with the primary winding;
- a relatively high speed rotary element, cooperating with two sets of permanent magnets, the flux of the first set of permanent magnets being linked to said primary winding and the flux of the second set of permanent magnets being linked to said secondary winding;
- bearing means for supporting said rotary element during operation;
- and
- means for simultaneously delivering the input and output of electrical energy to and from said primary winding and said secondary winding.
