Claim Text:
1. A method of operation of an electrical network configured to alternate power to an aircraft from a first generator to a second generator, the electrical network including an AC bus, a DC bus, a rectifier coupling the AC bus to the DC bus, a plurality of bidirectional converters comprising two linkup points, at least one link to link the first generator to a first bidirectional converter, the method comprising: powering the rectifier through a first generator, connecting the second generator to a second bidirectional converter and operating said second bidirectional converter to cancel a current originating from the first generator, delivering AC voltage to the AC bus by the first generator and the second generator, disconnecting the first generator, operating said second bidirectional converter to allow the connection of the second generator to the rectifier at zero current, connecting the second generator to the rectifier, providing a DC voltage to the DC bus using the AC bus via the rectifier, and powering a load of an aircraft by having each of the first and the second bidirectional converter being linked up at a respective first linkup point to the DC bus and being linked up at a respective second linkup point to the load.
