Electric power feeder for multistage gradient amplifier

摘要

The power feeder includes several rectifiers (26,26',26'') with switching units (30, 30', 30'') which are connected to an alternating voltage source (20). Electric power is supplied to the rectifiers when operating the alternating voltage source.During normal operation energy from the electric power feeder is received through DC voltage terminals (28,28', 28''). During feedback operation, the energy stored in capacitors is send back to alternating voltage source, by operating the switching unit
