    摘要: An electrical power converter for an incoming AC transformer connected to a multiphase power source and having multiple secondary windings. Each secondary winding is connected to multiple switching cells, each of which functions like a matrix converter. The secondary windings can be either single or multi-phase and more than one transformer can be provided such that the multiple secondary windings can be distributed among individual transformers. The output of at least two of the switching cells are connected in series. The switching cells can be either bi-directional or unidirectional and can also have a three-phase input. A combination of IGBTs and diodes can form the switching cells.

    摘要: An ion source is disclosed which utilizes independently powered electrodes that are isolated with a series of insulators. The ion source comprises an anode electrode with a hollow interior, where the anode is disposed between a cathode and an anti-cathode. A magnet or electro-magnet imposes a magnetic field in an axial direction through the bore of the anode. Gas is introduced into the anode area at a controllable pressure. The ion source includes a first voltage differential between the anode and cathode for the production of plasma and a second voltage differential between the anode and the anti-cathode for extraction of ions from the plasma, forming an ion beam, which is preferably of a narrow diameter at low beam energy. In particular, the voltage differential between the anti-cathode and anode is adjusted to control the initial beam divergence of extracted ions. An optional focus electrode with an independent power supply further focuses the ion beam. A final electrode defines the output boundary of the ion source to provide un-perturbed drift of the ions into the vacuum chamber.
